Here we have the first Guitar I've created. With inspiration from Psicojimi's headless guitars, and a fair bit of Google image searching! The Guitar is a fixed bridge, twin Humbucker setup and uses a Yamaha donor neck. There is a placement for a 3-Way selector switch, Volume knob, input jack and strap buttons.
The design has been split into six parts to allow printing on a typical 3D printer, and I've included both STL and STEP format. I've also included a fully assembled model if anyone has a large format printer, although this would require modification to the design to allow the reinforcing rod to be fitted (runs between the neck and bridge to take the string tension).
Files have been marked with their positions:
TL = Top Left, TR = Top Right, TC = Top Centre, BL = Bottom Left, BR = Bottom Right, BC = Bottom Centre. Control inserts are marked as Volume and Tone with T = Top, M = Middle and B = Bottom.
Assembly is pretty self explanatory, using the glue of your choice (I used JB Weld Epoxy Adhesive) to stock the sections together. The Centre requires a 290mm M12 threaded rod in the lower hole, which I epoxied into place for maximum strength.
There is a hole from under the bridge to the bridge pickup cavity to allow a ground wire to be fitted to the bridge to ground out the strings.
The Volume control insert goes in the hexagon connected to the bridge pickup, and the Tone control in the next hexagon (it's shaped so you can't get them mixed up). The volume control inserts are three part, to allow an ‘insulating’ layer between the switch and the POT for open type 3-way switches.
The Neck I used (and the pocket is designed for) was a Yamaha ERG 121, which I found at very low cost on eBay. The pocket may well fit other necks, but you'd need to test it out to be sure. The neck is fixed using a standard neck plate on the back.
The Bridge I used was a Musiclily fixed bridge purchased on Amazon, and the hole pattern is set for this bridge:

The pickup cavities are sized for standard Humbuckers, although the spacing for the mounting ring was set for some cheap Humbuckers I got from Amazon:

The rest of the hardware is standard size. The control ‘pods’ can take full size pots, and the switch is the standard size 3-way switches (Les Paul style).
