foots for drying rack, 16mm pipe

Small feets for drying racks, flower stands, cabinets, and other furniture with a 16mm tube at the bottom. They prevent robotic vacuum cleaners from getting stuck on the low tube (when it's on the floor, it's invisible to the vacuum cleaner's sensors). After raising the tube by 30mm, it's visible to the vacuum cleaner and doesn't interfere with it.

The legs are designed to snap onto the 16mm tube, but to prevent them from getting lost when moving the dryer, they have hole (tunnel) for a cable tie. 

If they get in the way, simply rotate the legs upwards, and the dryer doesn't become taller for storage.
