This is sized to work on my Be Quiet! Dark Base Pro 900 Silver rev. 2 Will work on other cases but you might need to resize it yourself. Do not use glue to stick this to your computer I recommend to use 2mm PET Acrylic Clear Double-Sided Super Tape to stick this to your case.

If you resize it in Tinkercad, remember to hold shift and drag a corner to right size.

I have good luck printing with and without supports. If you are printing the smaller cover, supports are not needed. I did have a few fail prints of the 44.5mm cover without supports.
