Furniture corner bumper washers

I have some bumpers to the corners of the furniture. There is some design problems with it. The holes for the screws are too large for the appropriate screwheads and there is no enough room on the bottom for a washer.  It designed to screws with 6 mm head but it is easy to modify in the Fusion modell.

Print two round washers to the sides and one cut to the bottom.

I printed them from PETG.
