Rostock Mount for Locking Ball and Socket

This is a doohickey for mounting DougLorenz's Locking Ball and Socket (https://www.thingiverse.com/thing:1393617) to a Rostock printer. At least, it fits on my Rostock MAX v3; I make no promises for any other model. It's got feet that slide into the mounting holes on the top of the printer and a compatible ball for attaching one end of the chain. Pretty simple, really. Comes in left-handed and right-handed versions. Remixed in OpenSCAD, because that's the way I roll.
