The Polycaster is a design I've been working on for a while and finally decided to print it. The main body is made up of 6 pieces that I've epoxied together. The main middle part was printed with 100% infill and uses almost an entire roll of filament. The outer 5 pieces were printed at either 15% or 25% infill, depending on the piece. The pieces that hold screws were 25% infill, and the rest of them were 15%. This way I was able to print all of those parts with a single roll of filament.

The neck pocket and bridge design were based on the specs of a 60s Stratocaster. With a 25.5" scale neck, you should be able to use any Fender Stratocaster neck or any aftermarket neck designed to be Fender replacement necks. I had a third party neck I ordered off eBay for a different project lying around, so that's what I decided to use.

This was a long one. All together, the total print time ended up being about 9 days. The main piece that is 100% infill took about 2 1/2 days, the other body pieces ranged between 9-17 hours per piece, and the rest of the components (pickguard, knobs, backplate, etc) took a handful of hours.

The neck I used was designed for a guitar with a much deeper neck pocket, so I had to shave down the neck joint a few mm for the strings to fit. But when that was done, everything lined up perfectly. I didn't even have to intonate it.

Some parts will need supports. The main part definitely since, depending on if you print it upside down or not, it will need supports either where the springs go, or there the neck and pickups go. The biggest body piece needed supports for where I've designed the output jack to be. The rest of the pieces should be fine.

Depending on which pickups you use, you may have to drill a few extra holes to make room for the wires. I ended up drilling two extra holes so I could route each pickup individually, but in retrospect, I probably could've made due with just one hole. The wires for the pickups I used were just a little thicker that most.
