Covered 3-layer BCAR

thingiverse

Update 9/8/22: Added looser-fitting cover after reports of overly-snug covers. This is a 3-print, 3-layer (9 bearing) BCAR for foam blasters. There are vents near the base to allow excess pressure to escape without fishtailing the darts. There are various angles available, and all use the same Cover and Collet prints, so feel free to print a few to test out which is best for your blaster. Similar to my 5-layer BCAR, the original idea was to allow a BCAR attachment to be printed such that the tip could be orange (for safety or legal reasons) while the rest of the body could be another color. Of course, if orange tips aren't needed for your use case, feel free to print all the parts in the same color. The cover should do a decent job of keeping dust/pet hair/etc. out of your bearings, as well as giving you a canvas to get artsy on. The base and cover are keyed so that the cover won't rotate. You'll need 9 of each of the following parts to complete this build: 3mm x 7mm x 3mm F683ZZ Flanged Ball Bearing 3mm x 14mm Steel Dowel Pin Both parts can be had on Amazon as well as Aliexpress or other retailers. Uses the Foamgasm Collet internally to retain the BCAR on the barrel (https://github.com/hooglanj/Foamgasm-Lynx-Mods/)
