This is a remix of some bed leveling knobs for other printers. I used the original ones on my Anet E10, and made some for my Anet E12 also. I found that the knobs were a little small and hard to turn when my hands were sweaty or had some glue stick on my fingers, LOL XD So, I decided to edit this model in 3ds max. I increased the outer diameter to make them easier to turn and make finer adjustments. I tried this version on my Anet E10, but they were a little too big and hit some of the other parts. These work great on the Anet E12 though! Much better and easier to turn!

Enjoy! :)
