Here is the next revision. Everything has moved to modifiers and I have started a youtube playlist showing how to use everything. The playlist will grow as I can add videos. But the general idea is that you add a curve from the blender assets then make a new mesh object like a cube applie the desired modifier to the cube and select the desired curve in the modifier

It’s a mix of Python and geometry nodes. The geometry nodes have added a lot of flexibility for the end user but are causing a lot of problems in terms of interfacing and producing reliable results.
-
I have fortunately/unfortunately uncovered a show stopping bug. Fortunate that I caught it now unfortunate that it needs fixing before I do release.
-
Another quick update. I have finished the initial set of geometry nodes and am currently working on getting everything tested and packaged together for the next release. I am also making a bunch of tutorials that will be released on the Photon and Plane youtube channel. I hope to have everything wrapped up and ready fpr the next release in the next week or two. Including a video of it being used for real world applications.
-
A quick update on things. I am integrating Geometry nodes into the plugin but there logic is really a bit loopy compared to whats standard. and no pun intended its throwing me for a loop (ok the pun was intended :)). but we are getting it and it will get in there just going slow. It also looks like I will have some additional blender tools/addons that will be coming out as a result of this effort. It just makes sense to split these things off into their own but will work nicely in conjuction with the Guitar Generator.

I haven’t heard any feed back yet on the add-on. I am posting an update here This should install just like the last one and overwrite it. Save the other zip if you would like to go back! This one as the main part of the neck being generated given a couple of neck profiles. I am not happy with the outliner organization and I think I may have found some additional tools that will make something better so there should be a large opverhaul coming in the next update which might take a while to produce.
That said if anyone has feedback on how it is now or even better how they would like to use something like this. NOW is the time to let me know!
The file size has gotten to big to post here, so yall can grab it off my google drive

I am using blender here. I would highly recommend this tutorial series to learn it https://www.youtube.com/playlist?list=PL3GeP3YLZn5hhfaGRSmRia0OwPPMfJu0V
and then I would do their game console tutorial. I would then look at artisans of vaul and blender bros videos.
I would also highly recommend getting at least the machinetools addon and if you can spring for a bit more the meshmachine and the hardops/boxcutter plugin

Awesome thanks for the feedback

I will agree with Ian. When I first learned Blender it was a slog but being a poor college student I couldn’t afford 3ds max or Maya even the student versions. Intuitive it definitely WAS not. That said once learned the hot keys make it like nothing else. I did eventually get a hold of versions of 3ds max, Maya, sold works and AutoCAD but went back to blender mostly because I was faster with it and I knew I could maintain it. But life happened and I eventually had to drop modeling (I was primarily doing it for video games at the time). Then I got into CNC and 3d printing after several years and needed to model again I grabbed blender didn’t remember the hot keys so was slow and now that I needed more precise Cad it wasn’t a great fit. I found SketchUp and it fit my needs perfectly. It didn’t have an affordable gcode export so I wrote one 2.5d for the CNC. And found a tool path for the 3d printing. It worked well didn’t matter if I didn’t use it for a few months as it was simple to pick up. It had a couple large flaws (like with booleans) but free, easy and did the job. Then Trimble bought SketchUp from Google and SketchUp went down the tubes quick and I found I would have to relearn a far less capable system. So started looking around again and was pretty set on going with rhino after resigning to inkscape ( a 2d vector program) for design work. It was just the $1000 they wanted for it when I am going to use it what once or twice a year. I tried Fusion and found way to buggy and clunky for my sanity. Tried others too like tinker cad, scad and a few others. I saw blender again and the massive amount of work they had done with the interface so tried it again and fits leaps and bounds better than it was still not the most intuitive but more than capable and they now have this adding system which someone wrote a cad sketching program on to give blender parametric sketching capabilities. That didn’t seal the deal for me though as I remembered what a pain it was to initially learn. So I was just saving up for rhino. I had tried the demo and liked it. What made me decide to switch was one of the 3d club videos here where they tried the different packages and a comment was made that others agreed with that to use rhino properly you really needed to learn the hot keys. Well sh.. if I have to do that I might as well go with Blender. And if I am going to put in that effort again I might as well (see the top of this topic 😀)

Just watched the knob tutorial. I thought it was complete but very quick. Great if you know what the tools do but not really helpful in figuring out how the software works to do something different. I was thinking of using mostly stock blender but likely with the cad sketcher add on.
I should have added I have used Blender extensively… about 20 years ago, and I haven’t really used it since. That said I have used other cad programs lightly as well so familiar with modeling/cad in general. In short, if I am going to go through the trouble of relearning blender for cad type applications I might as well make it useful for a larger group as well. I also have some ideas on how to tie it in Nicoletti’s and Gores concepts (I am a software developer with a Physics degree) but that would be years down the road if ever. As it is I don’t have a ton of free time so going would be slow but you know about slow and steady.

Definitely Stauffer inspired/influenced. The simplicity is very attractive. I will confess I am a bit nervous about getting the neck angle right and admit that I thought well since I was interested in an adjustable neck joint anyway why not kill two birds with one stone
-
@PaulMcEvoyGuitars Those are some nice guitars you make. I have the Gore/Gillet Books and while their neck joint looks very similar its a pure bolt on/off and doesn’t pivot. I have seen something similar to what you have before pivoting on the CF Pad. Unfortunately I can’t remember where I did and heck it may have been a post by you in another forum.
As for your design if I am understanding what is going on is that there are two bolts in the finger board extension. One that is used to hold the neck and body together and another that pivots the neck changing the action. Is there anything in the heel itself holding things together? the bolt on top that doesn’t adjust the action how loose/tight is that kept to allow for adjustment but not rattle? I am also assuming that the neck is held down with string tension.
As for the sliding joint I will definitely share anything I come up with. The links I posted above are all I have right about any of it. In playing around with the t track this weekend I have come to the conclusion there is too much slop to get a satisfactory neck joint in the commercially sold pieces. This is probably what Martin ran into as well and why he buys one piece commercially and has the other one milled then ends up fiddling with more himself to get a good fit. In any case Im going to try casting a fitting piece if for nothing else than for testing purposes so we will see how that goes. Using a simple set screw is an interesting idea too, sometimes the simplist solutions are the best.
I saw the mention of those basses in one of the martin threads and I looked briefly but didn’t see anything having a good view of the neck mechanism so thanks for linking what you did.

Cumpiano's Hardware Based Neck Joint VS Tapered Dovetail Joint - MIMF

That podcast is where I initially heard about it. I have found a couple other mentions of it elsewhere. I will add the links when I get back home.
I don’t have a preference really. I am just playing around with different joints to see how I like them and want to proceed. I played with the dovetail a bit this weekend and plan to play with a gore gillet style Bolton as well as another one I can’t remember the name of but will link to tonight as well. All that said I have heard that these vertical adjustment designs don’t affect the tuning as much (at all) and I like the greater contact between the body and neck. One thing I don’t like if for no other reason than string changes are joints that depend on the string tension to hold the together.
There was one other I was interested in and that was a Lambert that Chris Jenkins from Lamehorse mentions and uses. He mentioned he thought the mechanism might be going commercial several years ago but I haven’t found anything but that about it. I know he’s on here and was going to message him separately about it.
One final thing I want to make clear is that I am not trying to steal anyones IP or copy designs directly. Just trying to find what’s publicly available and to learn so I can make the best guitar I can in the most respectful way possible. So if something is protected etc please let me know that too so that I don’t accidentally step on toes. In Martin’s case he specifically has stated he’s not trying to obscure anything to someone serious about it.

I second Ian’s idea here. I did make a bass neck from 3/4″ blank. It worked but was uncomfortably close and the feel of the neck is off because of it.
-
That’s a great resource thanks for sharing it
-
Thank you for the reply. I will be sure to remedy this before the next attempt
-
I like it

I just picked up the Cad Transform 2 addon from gum road for blender and it works very well. No more snapping problems. I would definitely recommend using this plugin it does cost but is affordable in the $10-20 range
-
There are several free “add-ons” that allows cam functionality in blender. The one that immediately comes to mind is blender-cam. But for me personally since I use a laser getting it to an svg file is enough then I take it into the laser controller software lightburn which runs the laser.
You are right blender is definitely more oriented towards creativity than being precise but thats not to say you can’t be precise in it. Like theres a different plugin called cad sketcher that will allow you to do most cad things and use constraints. The biggest problem I have foudn thus far in blender is the moving and snapping things to the desired location. Blenders snapping doesn’t work as typical but I know of another plugin that does allow for that.
-
Thats great to hear. I will likely try this on my next build or maybe even on my current one as I’m not past the point of no return yet.

I haven’t tried fusions CAM aspects but there are several other cam packages that will take models produced by any modeler and generate the gcode with it. In my experience they normally take dxf, stl or obj files. If I were ever to need to take something from blender to CNC that would be the least of my worries. That said that is typically a separate package all together and another $1000 from what I have seen. Though some have some basic modeler in them (vcarve I believe is like this or vise versa like fusion) I believe he no has an additional package you can buy for Cam things but I may be wrong on this. In short not having a Cam package isn’t a death sentence but I definitely get the lack of convenience not having on is particularly for non professional use
-
I am not aware of any cam addins. That said some may exist that I am unaware of, I will keep an eye out for them
-
It’s a new build
-
I haven’t. Add Ons wasn’t even a thing last time I really used Blender.
-
Well For starters Blender is free for commercial use and is far better guaranteed to continue to be than fusion ever will be so the investment in time is more worth while. Blender has been around for 29 years (started in January of 1995) has been free that entire time and is setup well to continue on. The rendering is vastly superior both as you are modeling and when you produce a final render. And in my personal experience Blender 20 years ago has far fewer bugs and hangups than fusion. When I tried Fusion it drove me bonkers how often the program got in the way and I would have to look for hours for a work around and/or redo the model. Finally I personally found that modeling tended to be slower in fusion than in blender once you got to know the shortcuts. Now both will get you where you want to go eventually but the hassle to get there is the difference. Now the one big down side of blender is that it was always initially intended to be a modeling app for CGI, video games(even has/had a game engine inside of it), computer generated graphics and not cad type applications. That said because of 3d printing and the availability of CNCs, laser cutters there has been a lot of work to get those features into blender in the form of add ones hence CAD Sketcher.

I do not

Awesome thanks

I assume some tinted epoxy After the sides have been bent would be fine.
