Idea is based on that of logmett's design, but no part of his model was used (complete redraw.)

A tad more rounding here and there, very small dimensional changes, and the most notable difference is the loop hole is much larger to accommodate loop through snaps. which the original design was too tight for. 6/3/17 Minor update (there were a couple splines I didn't like in the mesh, vanity edit) and new render.

2/26/2018 I found that some of my ABS (Hatchbox) shrinks a lot more than the others. To compensate, I simply made a version scaled up 4% here: https://www.thingiverse.com/thing:2808260
