Tube chair floor glider

thingiverse

Floor glider for tube frames, 25mm tubesize, including a 5 mm fixing hole. These need a 20-22mm felt disc (5mm thick) to function well on wooden floors. These 'grip' around the tube while the pin keeps them fixated in position. I designed these to replace the 12 mm knobs that were in the same position and were simply to small to hold a pice of felt glued on top of them.
