Hardware design files
The BallBOPPer™ mechanical CAD, wiring diagrams, and bill of materials will soon be published so builders can fabricate, inspect, and improve the rover, launcher, and reloader modules.
Hardware designs come in three forms:
- 3D models that are intended to be printed in an engineering material
- 3D models that are intended to be CNC'd out of aircraft quality aluminum
- 3D models that are intended to be CNC'd out of flat sheet plastic
For 3D printing, we have always used Polycarbonate. Many 3D printed plastics will shatter into a million pieces when dropped by accident. We opted for polycarbonate after watching a demo of a 3D printed polycarbonate hook being used to lift a 2000-pound pallet. That is the kind of strength needed for these engineering quality parts.
We will have more information on 3D printing polycarbonate. The strength of the material does make it harder to print.
Many of the 3D printed models, and some CNC plastic models are available now and can be found at: BallBOPPer Hardware 2026
Unfortunately, they aren't going to make a whole lot of sense yet. We will be adding some assembly models shortly that will show how the parts go together for each component.
The CNC aluminum parts are framing parts and those files will be uploaded soon.
