did the trick for some cardboard spools I had, no gasket needed.

This may be the best print I'll ever do. quality is great and the design is extremely well though out between the tools color matching (I did have to change them but kept the tools / screws / slots matching), and the shape of the holes only allow for the correct screw. My toddler absolutely loves it and I'm not currently using the wall mount but I will soon when I get a toolbench together for him.
