Made one in purple and black,
The original instructions said use #4x40 1 inch machine screws, but I found without drilling out the holes 1 inch screws were too long even with the ones that I found where the heads do not fit in the inset holes. for this one I used 3/4 inch machine screws.
Glass build plate with Hairspray,
I have done a few of these and found to keep from warping I needed to add some helper circles to the corners to keep from pulling away from the plate. the one pictured was not printed with the circles and if you look at the black portion toward the power supply you will notice slight warping..
