After seeing the plethora of cube-shaped coin traps on Thingiverse, I decided to make some based on the five Platonic Solids: tetrahedron (4 sides), cube (6 sides), octahedron (8 sides), dodecahedron (12 sides), and icosahedron (20 sides).
When I showed my wife one of these, she remarked "that's one of the most useless things I've ever seen!"
She has a point. They were fun to make, though.
The geometry of these shapes consist of balls connected by bars. Due to that, they need support around the base due to the small contact area each object has with the printer build surface. I recommend using a support enforcer cylinder (available in Slic3r or PrusaSlicer) to support only the base and not the interior of the objects.
Print this as a single object. Don't separate them! They are positioned so that the largest diameter hollow space is the same height in each object, so you need to pause the printer only once, carefully place a coin into each one (making sure that the coin is
