I just designed and printed my first 3D object.
I have several window mounted cat shelves throughout the house. They are held in place by a series of four suction cups. There are two cups that provide support for straps that hold the bed parallel to the ground and create a surface for the cat to lounge on. This design means that these strapped cups provide most of the support to keep the bed’s occupant resting comfortably in a sunbeam and not catastrophically dumped into the floor. To that end, they have an outer plastic shell that holds the strap in place as well as providing reinforcement for the suction cup underneath.
