Liked the design of this BCAR, but I prefer the way the EX BCAR attaches. Adds two different ways to attach them.

I only did the 8 degree as a remix for now, as I feel like that is the most standard twist for around 200fps. I can pretty easily add all of them in the future if wanted.
2 different kinds of attachment methods:
EXBCAR Rev2 threading: just thread it on to your existing EXBCAR mount, might look a little silly because the new BCAR is bigger than the EX. Print at .2mm
Integrated collet: took the collet from the EXBCAR and integrated it onto the new BCAR. This one looks cleaner, and is smaller lengthwise, but requires a bit more slicer settings to print correctly. Print the Collet Screw at .12mm. For the actual BCAR piece, you can either just print the whole thing at .12mm, or print at .2mm add a height modifier in your slicer (right click on item in bambu, height range modifier) from 60mm to 82mm. Then you can change just the threading to .12mm layer height.
I printed all of these with 4 walls, 20% infill, no supports.
