Maker Select Thumbwheel

I found the stock metal thumbwheels on the Monoprice Maker Select to be difficult to adjust with the back wheels. I made these thumbwheels with a couple of cool features.
1) It has a larger retention knobs on the wheel. This makes it easier to turn.
2) I added a raised (+) and (-) indicator so you can visually see which way increases (raises) the bed.

You need 4 M3 nuts. Regular is fine. No need for locking ones. I simply unscrewed the stock metal thumbwheel and place the new one on. No need to take everything apart. You're just swapping out the thumbwheel.
