Bed Leveling Wheel with M4 Nut

thingiverse

I had tried the [CR-10 Ultimate Leveling Knob Attachment](https://www.thingiverse.com/thing:2408748), but the holes seemed too small to insert the stock thumb screws. I tried rescaling the hole, until I detected that the wheel was obviously designed for different knurls with a different number of ripples. So scaling would never solve the issue. Therefore (inspired by that design) I created my own thing, directly with its own M4 nut. I decided to make the wheel just a bit smaller to avoid any interference with components under the bed. And to save on filament I used fewer and thinner spokes. The standard M4 nut can just be pressed into the hub - no glue required. At least that worked perfectly fine for me. Remark: After having finished by work, I found another wheal design for an M4 nut, the [Creality Bed leveling wheel replacement](https://www.thingiverse.com/thing:2408748) by [SimonRob](https://www.thingiverse.com/simonrob). It is smaller (requires same amount of filament though), but seems to resemble the wheel of the new CR-10 V2, so I tried that as well. But although the description said "_You will have to hammer in place a M4 nut into the wheel_", the nut went in quite swiftly .... and the wheel fell off after mounted on the printer. I didn't want to use glue, so I decided to stick to my own design :-)
