Magneto-X Bass Guitar

This model has internal features that force the slicer to make strong ribs along the string path.

 

I recommend printing with 0.5mm line width, 0.2mm layers, 8 wall perimeters, 20 top and bottom layers, and with a unique top pattern, such as Octagram - perhaps with 2-color filament and 20% cubic infill. This will give a 4mm thick shell and a 2.5kg final weight, which is about what a Fender PB body weighs. I wouldn't go over 9 perimeters (at 0.5mm line width) and 25% infill as it will get too heavy - heavier than a full-size wooden one.

Requires a printer of at least 300x400mm, such as the Peopoly Magneto-X, ELEGOO Neptune 4 Max, Anycubic Kobra 2 Max, Anycubic Kobra 2 Neo, or similar. Takes 1.5 days on the Magneto-X but could take 3-8 days on a bed slinger.

The bridge I used comes with 3mm screws and they are nice in that the heads are flush, but I feel like they are too small and short, so I didn't use them.

I used six stainless-steel wood screws for the bridge, size #6 x 1.5" Note: The pickup screw holes should be cleaned up with a drill bit of about 0.96-0.10 diameter or else it is easy to break off the screws in the hole. The #6 wood screws for the bridge will need about a 0.115 drill bit. I broke one of those off and you don't want to do that. Ideally use real tapered wood-screw pilot bits. 

If you do break a screw, remove by heating the screw with a soldering iron and backing out with a needle-nose pliers. The Vise-Grips kind are best. I had to drill out an area and fill with JB Weld - so I urge you to not make the pilot holes too small.

I am including a STEP file so you can make needed changes to fit your exact neck. The bridge hole pattern fits this bridge:

I recommend plenty of glue stick and a brim to keep your corners from lifting. My full quality print lifted the magnetic plate at all corners. Clamp the plate down if you can. Use side panels if possible.
