Alfawise U20 Add-ons

thingiverse

I needed several components for my new Alfawise U20 printer. The Alfawise U20 printer is still far from being a "CR-10 killer", but with some work, it has great potential as a competitor. The spring washers are quite straightforward to use. I designed the bed jack as a tool to slowly level out my bed. When my Alfawise U20 arrived, the bed was tightened down so tightly that not only the bed support had become curved, but the bed itself had about 1.5-2 mm of sag in the middle. I simply placed it under the bed and re-tightened until the bed became bowed in the opposite direction. After sitting for a while like that, the bed was almost completely flat again. The z-extender is intended to remove 3mm from the z height so the bed springs don't have to be tightened all the way down, preventing bed warp.
