Threaded cup with holder for toy board or other thin boards eg. kitchenette (70mm hole)

Cup with holder for toy board (70 mm hole).
Secure, versatile, and easy to clean – screws together tightly with no wobbling.

This cup is designed for a 70 mm diameter hole in a toy board, but it can also be used for other purposes like play kitchens or other organizers etc. The board should have a maximum thickness of 7 mm.
To mount it, place the holder from above into the hole and screw the cup from below against it.

This way, the two parts clamp the board securely from both sides, so the cup sits firmly without wobbling. For cleaning, simply unscrew the cup from the holder.

Note: If you prefer to use it by just hanging it into the hole, make the hole slightly larger than the cup, so the two parts can be twisted together and hooked into the opening from the top.
The outer diameter of the cup is 73.3 mm.

I made it from PETG but you can also print it in PLA. No supports needed.
