Bathtub Shelf

This is a shelf designed to slide over the low wall of a bathtub so that my kids could pour water onto things on the shelf without the water running over the side of the tub. My bathtub has a lip/wall that is 110 mm thick.

I printed this on a CR-30 printmill with supports under the legs.

Free-cad files are attached, the param spreadsheet can be used to adjust the width and the depth for different-sized bathtubs or printbeds.
