Sponge can for kids blackboard (Schwammdose fuer Kindertafel)

I created this sponge holder because the original one that came with my son's chalkboard broke. The holder is designed to secure a sponge using its sharp edges. The cover screws onto the can, preventing the sponge from drying out. You can see how it works in my pictures. I've included the STEP file for reference.
