Tolerance Tester remake from MMuse

Figured I'd put a spin (not a fidget pun) on the tolerance tester Makers Muse put out. The print is a great idea and I almost downloaded his. But I like to design and wanted to try a curved socket. So I put a gentle curve at the tolerance interface. Plus I added a chamfer on the bottom to handle those pesky first layer squish issues. The crank interface is a 6mm hex and I've got a draw of those so I used it. I probably only need a few sizes for my .4 nozzle machines. Say .2, .15, .1, and the unicorn .05. But the .8 rig might be different.
