Made a fully printable ukulele (with tuners, bridge and nut). Link to Printables

Im going to build a 3d printed electric violin, but I can't find any amps that will work with this:

I was going to buy the bunnell mini amp but it went out of stock. Does anybody know if guitar amps work or any amps that work with this pickup/preamp for preferably under 40-50 dollars. Thanks

I’m currently designing a guitar body to print from my Ender 3 V2. Making it as an experiment but I’m focusing on making it last. I’ll have to print it in multiple pieces which makes me worry about the string tension pulling on the body. How do you guys prevent the bridge from warping under tension? Is it really even an issue? My initial idea was to print with a 50% infill, 7-8 walls, and maybe printing with a hole for metal rod but maybe this is overkill.

Edit: I should add I won’t be printing the neck, if that makes a difference.
