So far this has been untested, but should theoretically print fine. I don't know the print settings I'd use yet, but I'd start at 2mm resolution and 20% infill. I've included files for the complete object, and each half, but they should be printed at the same time, since they inter-lock.

Update 1/29/2019:
I printed this last night, and was unsuccessful, the tolerances were too tight, so I've loosened things up a bit and redesigned the latch, since it came out all wonky. I'll leave the original file up for those who want to try it and upload v2.

Update 1/30/2019:
Printed again this morning and was mostly successful, noticed a few errors I'd made during modeling, and fixed/re-uploaded as v2. Should be the final version.
