Tevo Tarantula Thumb Nut for Bed Adjustment

thingiverse

It's incredibly easier to turn than those small knurled nuts that come with it. Additionally, this tool works well as an adjuster on the optional Pro Metal Extruder. A nut is pressed into the hex and screwed onto the existing bolts. I place a washer between it and the bed mount plate, and the nut you pressed in should be at the bottom to hold everything together. They were pretty snug so some heat may be necessary when assembling.
