Hex inserts for Cikro's excellent PSU support replacement

The tolerances on these are tight enough to press in against a flat surface for me. You may have to adjust a bit for your own printer.

There are three variations, the short one fits the bottom where the mounting screws are, the one with the small notch fits the second row where the support blocks part of the hole , and one for all the rest. 

Thanks Cikro for the excellent replacment PSU support !
