About this 3D model

New barrel for Hammershot. I don't have access to one at the moment. The design prints but takes forever. I'll release one without all of the cutout sections later. The dart in the picture is a micro, this is actually designed for the elite darts which are smaller in diameter, just didn't have any handy. Edit: due to shrinkage the darts don't fit in properly. I'll rework and reprint when my new set of calipers come in tomorrow. I can also test for fitting and indexing then.
