"ex" bcar barrel mount

Plain barrel mount for the “ex” bearing centering and rifling devices. This piece comes ready to print, I would recommend a brim at least on the main portion as you will see there is very little surface touching the bed. unfortunately it is not designed to print upside down.

Added 15mm Barrel Mount and 17/32 Barrel Mount files(These are technically beta files, let me know how they work for you.) 

It is important all of these parts are printed at a .12 layer height. The female threads do not like to print at higher layer heights, additionally these are high tolerance pieces. If you fail to print at the correct layer height your parts will not come as I designed.

UPDATED 9/4/2023: 16mm Thread Mountv2, has "ex" knurling on the mount.
