Stack your shoes.
Quite large to accommodate mens boots.
Unfortunately untested. Hope your layer adhesion is on point!
Print in PLA, assemble using superglue (cyanoacrylate).
Print the hub on its front (with square hole facing plate)
Print the other two plates in a reasonable manner (flip to eliminate overhang)
Picture shows two older prototypes. Current model is most similar to the gray one but with better plate interlocking to make gluing easier. The grey version relied on filament pegs but did not work very well, and the pink version required too much glue and was difficult to assemble.
Overall, imo not an economical use of filament since for this to work, you'd need to print multiple.
