I started a 3D printing company generating on average about 2k/month printing small plastic clips and connectors for collectors as well as a few other adapters and jigs sold on eBay.

I'm now working on building out a 3D printing course teaching others how to do the same.

I've heard of people doing this with RC car parts. What printer do you use?

Yeah I've seen a few people doing that. Nerf mods are popular too.

I have 3 Ender 3's. They're easy to mod and work great if set up well.
