After cleaning running shoes, you want them to dry. You can of course put them on their side, but that just looks so ugly. So, here's an alternative: this stand allows “hooking” the shoe with the back into the holder and it will lock in by its own weight and then float above the base.
Obviously you will need to print 2 of these if you want to float a pair of shoes.
Works fine for our shoes, but depending on your shoe size, might require some resizing. I have included a STEP file in case someone wants to build on this. Also included the 3MF file for my Sapphire Plus.
