A hard case for a CC3D board (OpenPilot). This one has survived several crashes as can see a heavy one in photo, case came unstuck from 3M pad in crash, bounced around a bit but fine, and most importantly CC3D is OK!I Designed case as I was finding my Rapman 3.1 was not printing the other designs around that well, this one is fast to print and solid, it's designed for FDM printers. Has LED hole for status LEDs. Use M3x15mm anything.3D Print it! Use your favourite plastic to build, case in photo is built with layer thickness 0.5, use your favourite settings though I prefer thicker layers and lots of flow/heat for objects that need some solidity.
