Both chuggers have standard GD tuning (same octaves)! 15.25" and 23" scale lengths, Classical and nickel wound strings, Piezo and Shane Speal Snake Oil Humbucker. 3D printed guitar and off the shelf shovel. Super light and super heavy.
Both lefties, so I can play them!!!

Thanks Uncle John! Never planned on the shovel guitar as I don't really have the skills or tools to work with metal and got away with only needing to drill 4 holes through the shovel. But glad to have done one! (A rite of passage?) The Mini Chugger is more up my alley and has been fun to design. For Version 2, I will show all the parts and do a video.
Pretty cool, Doug.
Version 2 will be fun to see. Enjoy the journey :) -Glenn
Thanks for the good words Glenn! It's fun trying out different ideas. Version 2 of the mini is almost ready to print.
Doug, cool on the shovel but I LOVE that mini! Sweet! You're imagination is producing fun stuff bro.! -Glenn
I appreciate the interest BrianQ. I have been inspired by the various 3D designed and printed ukuleles on Thingiverse, but all the 3D printed parts on this guitar are my original designs done in OpenSCAD, an open source (free) design program. A lot of trial and error is involved because of the limitations of plastic under tension. By the way, I have figured out out how to incorporate a small disc piezo into a 2-piece bridge that allows more string volume and less top sensitivity. I'm still working on the updated body design and added tailpiece to handle all the design changes. The next version should be much better. Note: if/when I get a larger format printer, I might attempt a 3D printed guitar with a longer scale length. The headstock bolts on the neck and the neck/body is 2 parts joined by a dovetail (which the slicer does for me) on the neck with a carbon fiber rod holding it together. The fretboard with frets is 2 pieces and secured with double stick tape (which works very well).
I forgot to ask, did you use a template file or did you design your own program file for the 3D printed guitar?
I have at least one rod piezo on hand and that is what I may end up using. I have fitted them in 3D printed bridges before. Thanks for reminding me BrianQ. I'm going to try an experiment with a smaller disc piezo doing something along the lines you suggested first, but the rod piezo may end up being the more effective choice. Thanks for the input!
Maybe you could print something that would encapsulate the disc to shield from the extra noise? Have you thought of using a rod piezo, I'm sure it wouldn't be hard to fit it in a 3D printed bridge?
Thanks BrianQ! This my first attempt at a 3D printed Mini Chugger. It works surprisingly well. It's quiet unplugged and sounds great plugged in, but ... the piezo under the small top makes it super sensitive to the pick hitting the top and the strings are too close to the top. It's hard to play clean enough to not generate extra noise. That is the big issue I'm working on. I have resolved the string height over the body. I still,have to rework how I'm using the disc piezo and I have a plan. For Version 2 I will include more pictures. I'm also working on making it so that it can be assembled right or left handed from one set of parts. It has the scale length of a concert uke, but should fit in a soprano uke gig bag.
