Superstruts improved back plate

This is a quick remix of the Superstruts by jumpshoutmedia (https://www.thingiverse.com/thing:3479330). I found the back plates to be very challenging (ok, hard as hell) to put on as there wasn't clearance for either nuts or socket drives to tighten it all down. In this remix I simply widened the cutout around the where the bolts will pass through so you can get tools on them without cursing too much.

This should be printed on edge, doesn't matter which, without supports though you may want bed adhesion like a small brim.
