Rebar/Roxor Knob/Cap by katysramkova

Reupload of my preferred rebar cap.

Original description, not mine:

Ever almost got spiked to a steel reinforcement bar during a house construction? People here use plastic bottles to cover it to prevent injury. I use the same bars at my garden and I almost once stuck it in my eye, so I invented this knob/cap to cover it.

Printed on my Prusa Mk2 i3 printer. No supports needed.
