Kitchen and bathroom sink strainer

This sink strainer is a remix of the one designed by gratefulfrog because holes were too and it was collapsed too easy.

Its size is the same as the remixed one:
- Depth 10 mm
- Interior diameter 40 mm at base.

This sink strainer is made for 44mm sinks. I haven't added the external plate because I consider it useless. I've removed lateral holes because they got dirty in a few days.

It may not support boiling water if you print it using PLA.
