Basement drain adapter

This is an adapter if your drain in your basement is misaligned regarding height with the surrounding floor. If you add insulation in your basement and the floor level gets higher, you need to take care of your drains. This adapter does the trick. Just buy 3mm plastic sheets in an Hardware Store of your choice and Print the parts to set up the whole adapter. The plasic sheets should fit tightly so no water gets through. If you want to be safe, glue the sheets in with silicone.

The current version is for drains from Kessel, which are very common in Germany.

The height is for a standard floor foundation of ~12cm

I also added the Freecad file if you want to adjust anything.
