Trion BCAR

A BCAR for your Trion. Attaches to the orange plastic muzzle attachment point. The first few times you attach/detach it, it may be very tight on the last little bit, but it should wear in to be a snug-but-doable hand twist. If you can't get it to snap into place, there are four tiny nubs at the very base of the inside that you can lightly file to make it a little easier. These nubs are what engage against the corners of the Trion's attachment point to keep in place, so don't completely remove them.

Takes 9 F683ZZ (3mm x 7mm x 3mm) flanged ball bearings and 9 3mm x 14mm steel pins. These can be had on Amazon, AliExpress, and numerous other outlets.

Print with the muzzle pointing up, and supports on the buildplate only. The face that will eventually brace against the Trion's muzzle is horizontal and needs support, but that's all.
