Bathtub Crayon Holder

A simply holder for bathtub crayons and a sponge!I think most bathtub crayons are a very similar size (if not, let me know, easy enough to modify), but I built this to hold crayons with an OD of 14.5mm and an ID of 12mm One problem my kiddos always had is the crayons sit in water somewhere and turn to mush. This holder is open on the front to allow drainage, and the sponge holder also has a drainage hole. I printed in PETg for some durability and heat resistance - but I think PLA would probably work fine as well! The top has a threaded M5x0.8 hole as I happened to have some suction cups with a thread on them (listed in the BOM). I'm happy to make some other suction cup mount designs if needed, otherwise, let it sit on the edge of your tub!
