US Amazon Prusacaster Four Mounting Holes

This is the kit you will need to purchase for printing this:

It shows 3 holes for the bridge on the Amazon page, but it is four.

Story

The Prusacaster was always one of my dream 3D printing projects, but there was one problem. The kit that Mikolas Zuza recommended was shipped from the EU, so the shipping cost more than the kit itself. I looked through the remixes and found this model by Mike-Print. The kit required for it shipped from Amazon, and was a cheaper total price. Once I got the model, I printed a test print to see if all of the mounting holes matched up... They didn't. The kit must have changed over the past 3 years, and the bridge had four mounting holes instead of 3. I tried converting the model by Mike to a STEP file, but it wasn't working. So I decided to start from scratch with the STEP files Mikolas Zuza provided. 

Changing the mounting holes for the bridge was pretty easy, but the neck was not as simple. The kit was pretty cheap, so the neck mounting holes were all wonky. I tried to get the holes to match up with the neck holes, but then I realized I could base it off the neck mounting plate. Basing it off the neck mounting plate would be better for other people trying to print it, since it would be more uniform. After 500 grams of test prints, I got it right. All parts matched up, and I could start printing.

Details

I modified the main body part, and the pick guard to work with the kit. There are two models for the pick guard, one is a plain one and the other is one with hexagons inspired by this model. Just want to say that this is not a remix of it. I tried to modify the stl, but it didn't work so I just made it to look like the original one by Tekjock.

You will need to print some models from the original Prusacaster, the orange body parts, the part that holds the tone and volume knobs, and the blue accent piece. Feel free to use any colors you want!

!WARNING!

Your neck mounting holes are probably not very uniform. If they don't match with the 3d printed part it is okay, just screw the screws through the neck mounting plate and the part.

All STEP files are included. I don't think it will change for awhile, but you should be safe and do a test print before you start printing everything.

I would recommend reading Prusa's article and video to get as much info on the build.

And here is Prusa's Video on their Prusacaster build:

Assembly

Putting the Prusacaster is pretty straightforward, but I will list the build process anyway.

1. Glue everything together and and screws to the orange pieces if you are doing that.
2. Connect all of the wires together and make sure the grounding cable is through the hole near the mounting of the bridge.
3. Screw all of the electronics into the body with the provided screws as long as the grounding cable will touch the bridge when screwed down.

4. Then you can screw on the neck! WARNING! The screws in my kit snapped when I was screwing them in and I would recommend getting some nicer ones from your hardware store.

   

After you get the neck screwed on you can string everything up! If you want the head stock to look like mine you can download this template I designed for routers:  Head Stock Template

Just want to say that I had to get new saddles because one of the height adjustment screw holes was tapped incorrectly and it wouldn't get high enough to work. Here are the ones I used: Amazon Link

Print Settings

Mikolas Zuza recommends printing with 7 walls and 25% cubic infill. I also used the Structural profile in Prusaslicer for extra strength. Besides those settings you can keep the other ones mostly the same. Also add supports to the main body part and any brims if you think it is necessary.
