Just a quick remix of @chuyskywalker's version to increase the width a bit so the fan went in with a little less force. Also increased the offset of the stop from -7mm to -9mm

History:

2023.03.25 - Added two alternate versions, increased offset height by 1 mm, decreased size by 0.05 mm to get a little snugger fit, added stops on sides.

2023.04.30 - Added 37x21mm version for P1P (untested by me as I don't have one)

The other alternate increases height offset by 1 mm and decreases the size by 0.05 mm
