There are a bunch on here allready but I made my own since I wanted to know the screws i had (25mm) would protrude the right distance into the door (11mm in a 16mm thick door) and that the fit would be right for my lids. 3 sizes with different thickness at the edge.

All three sizes remove 14mm from the screws so there is consistent grip withoout poking through the front.

Small is made for a 157mm diameter lid 8mm at the edge Medium is for a 170mm lid 13,5mm at the edge and 20mm thick 30mm in from the edge Large is for a 195mm lid 22mm thick at the edge and 24mm thick 30mm in.

The diameter is not that critical, important part is the thickness. if you want tp print it for your slightliy different lids just scale the thickness a bit if needed, but mind the screw lenght if you change it too much.
