This is a drain guard for catching hair and anything else that might go down and clog a not well guarded drain. The model is 30mm tall and 42mm in diameter so you'll have to skew it before slicing to meet you needs. I designed this after trying a preexisting model from Thingiverse and found it worked a little too well. It did stop hair but it also slowed down water draining too much and caused it to pool up. This has lots of hooks pits to grab loose debris falling in the drain
