Laundry Rack Riser

Easy-to print riser feet for standard laundry rack (about 16mm diameter tube).

- rises the rack enough to trigger robovac collision sensors (tested with Roborock S5)
- still allows folding
- better floor protection
- no more lost clips or clips facing in the wrong direction
- glueless & screwless assembly with cable ties
- easy print for flex / semiflex (PLA is fine for pins), no supports
- slightly parametric (tube diameter and spool diameter)
- provided stl work perfectly for the standard rack model

I made mine from Fillamentum Flexfill 98A. The pins are only needed for centering, probably some cardboard slips will do just as well.
