The Lost Pawl JR Double Cut Kit Guitar

Ever had a dream about a guitar but didn't want to spend thousands of dollars? Like to tinker and build? Here's a fun project for ya. 

Printed in PLA on a slightly modified Ender 3 V2 with a 1mm nozzle.

The design is based on a 1959 Les Paul Jr Double Cut. 

This model is a total of 13 components that uses some loose dovetail joints as a mounting guide. The joints are not meant to be structural, they have good tolerances meant to act as a fixing point for epoxy or glue.

The neck that I purchased is setup for a 25.5 inch scale, the original neck is supposed to be a 24.75 inch scale. In order to get this to work I modified the neck joint to be similar to the original design, but fit my cheap neck. This extends the neck joint out from the body about 2 inches to make up for the increased scale length. This had to be done to keep cost of the neck down and have a playable instrument. Remixing the neck joint component for your specific neck should work and is encouraged. Keep in mind the scale length. I strongly suggest you print this at 100% infill because most of the string tension will be on the joint. 

Obviously the hardware is purchased, at least everything that was not practical to print. However, stay tuned for a future project of a printable guitar neck (if it works). The bill of the hardware I used is linked below. All of it is purchased from Amazon (AliExpress should have similar if not the same stuff). 

The whole kit (including 3 spools of filament) cost me a total of $190. The majority of the cost was filament, which I purchased new specifically for this project. You can tune infill and settings to use less or more, but my build was mostly 70-100% infill. 

Tone and volume knobs were made by Qrone. I snipped a small piece of filament and heat pressed them in for some contrast.

This is the wiring scheme that I followed, but there are other configurations. I believe this was how they did it back in '59

The Shim components are so that you can customize the build as you see fit. The pitch angle of the neck will change depending on a lot of factors, that's why I opted for the shim approach over a static angle. On my build I am at about a 3 degree pitch using the 3mm shim. I have good string action with the bridge that I am using and my string innotation is pretty spot on. Included are 1mm and 5mm shims just in case someone wants them.

Explanation of guitar scale length:

If you made it down this far, you probably are realizing that I have a Fender style neck (with Gibson style headstock). This was kind of intentional. I love maple fretboards. Longer scale is easier to play. Plus they are insanely cheap and easy to get as a replacement neck.
