BcS Umbra SBCAR

Collet free modified version of Umoya SuperBCAR from WaFfLe and ZaC

I tried my hand at polishing up a few corners here and there, and tried to match the aesthetics of Rexfires Axiom.

This is strictly only friction mounted, so you will need:

Note this is a tight fit with a 16mm Barrel, but it is supposed to be :)

18 x F683ZZ Bearings

2x - 016 O-Rings

18 x M3-8mm or M3-10mm Flat Socket Cap Screws (Ultra Thin Super Flat Screws work great as well)

(Alt standard socket cap screws with M3x8 or M3x10 will work if you don't have flat heads.)

I recommend printing with a brim, and tree/organic supports, with top or bottom orientation, base on the bottom seems to work the best from my test prints.
