Fractal Vice Version 2

* Improved/updated version here - https://www.thingiverse.com/thing:4922759 This is (should be) an improved version over the earlier one. Instead of the dovetail connections between the pieces I've drawn it with simple 90° & flat surfaces that'll print more cleanly & the supports will (should) also be removed easier. To give enough space to make it all fit together I've made the sliding connections between the pieces stick proud of the outer radius of the semicircular parts. It's not as tidy as doing it with the dovetail sliding connections draw inverse to that, but it'll work better on a 3D printer. On the mounting bracket I've added four of 10 mm holes in case anyone actually builds one and wants to bolt it down onto a bench. I will be drawing a sliding frame that'll finish off making it into a complete & otherwise conventional vice. That'll happen hopefully soon. You'll need fourteen 3 mm bolts to lock the smaller parts together, and trim them all to the correct length
