Rostock mini glass bed support/level adjust

After few months printing discovered heat made the circular acrylic piece that came with kit, warped and became concave, so pieces were attaching poorly, decided to replace it with a square borosilicate glass (200x213x3mm) plate.
Made this pieces to attach the glass to printer and, by using 2.5mm nuts and bolts, can level base more easily than it was on original design
