This is my attempt at designing a supportless shoe stacker with low filament usage. PLA compatible!

I plan to play around with the thickness of the walls/ceiling, to see how low I can go before it gets unstable. I also want to make a version for higher shoes in the future.

Simply align the top face with the printbed and print!

Note: I screwed up a bit in the design process, so that the model is now just barely larger than 25cm, and thus too large for e.g. an MK4 print bed. Scaling the model down to 98% solves this easily. (I also plan to reupload a fixed version soon.)

The stacker in the photos was printed in 4h22min with the “0.2mm SPEED” profile on an MK4, using a 0.4mm nozzle and Prusament PLA Galaxy Black.
