These are parts for the Hyperlite Floss. The parts for standoffs have a "cap" to them that is 2mm. This raises the top plate a little and provides some cushion in a crash.
I HIGHLY recommend using a washer for the top camera mount screws. which should be m2x4. It's designed for the runcam mini. If you use m2x6 or larger you may damage your camera board. This has nothing to do with my design just use caution and common sense.
The shark fin is to hang antennas to protect them.
The wire covers are sized to BARELY fit 2204 motor wires. If you have 18g 2206 wires or larger you may have to stretch the design.
I printed on a prusa mk2s with sainsmart TPU. 20-40% infill honeycomb works great.
