I'm not sure if anyone cares about this or not...but I figured I would throw it out here.
For a long time I've been using those rubber "casters" that protect my floor from the metal leg levelers. The problem with them is that they don't really allow for you to move the machine that much. In fact, it sometimes feels like I am tipping it rather than sliding it. Because of this I decided to come up with a 3d printed cup which holds a standard felt furniture pad. Before you ask, I tried to use the felt pads by themselves, but that doesn't work because the levelers move and the pad eventually slides off.
So, basically I print these little cups in TPU, then jam a standard felt pad into them. They seem to be working pretty well, but I need to test them over time to determine how the felt wears.
The felt pads cost about $0.35 each and I estimate the TPU used to be $0.65 or less. Overall I think they end up being $2-3 less than the nylon leg levelers. Also the felt is replaceable unlike the nylon.
If anyone is interested in this, let me know.
