Just installed a wood floor in the craft room where my grandparents old Singer Treadle Sewing Machine lives. I was worried about the little 1 3/8" diameter metal wheels on my new floor so I made Castor Cups for it.

I set the Infill higher than normal because of the weight of the machine. (Probably over-kill)

Additionally, I added stick-on felt pads to the cups so it would not slide on the floor so easily.
