Shown: an earlier prototype revision — the current CBR5CSR3890 is in final testing and the purchased file is always the latest version.

What you get

  • Print settings that match our production parts (material, walls, infill, inserts)

What you don't

  • No electronics — V-mount plate, D-Tap connectors, switch, and wiring are on you

  • Personal use only — printing to sell copies isn't licensed
