Chair Caster felt holder

thingiverse

I have a hardwood floor, and my office chair with caster wheels is not so good for this type of flooring. I used to have a small rug just so that chair could sit in one place without causing any damage. Instead, I designed a small felt holder caster cup which can slide into the place of the wheel, securing it firmly in position. It has edges that fit snugly inside the end of each leg, providing stability and preventing movement. To use this solution, you will need to print five of these cups, which should fit perfectly together. Then, cut a piece of felt - large 4"x4" felt pads can be purchased at Home Depot - and stick it to the underside. Now, my chair sits safely on the hardwood floor without moving an inch.
