Backplate for Railcore 2 Printed Door Hinges

This is a backplate for the hinges of the RailCore 2 doors.
I was not excited to tighten the nuts on the back of acrylic and relying on bolts in acrylic to hold up to the constant opening and closing of the doors, so I designed a simple load spreader, which also helps to hold the nuts when you tighten the bolts on the other side. This is designed for nuts to be partially pressed into the part and 12mm M3 bolt to stay inside the nut for no sharp parts sticking out. Works with 1/4" acrylic.
