Acrylic Hictop i3 bed leveling thumb screw - 16.4mm
thingiverse
The thumb screws I've found on here have all had slight problems. This one looks a lot like the best one I've found, except they're thinner so they can pass over the front piece of acrylic holding the Y-axis rods. This is thin enough to get past it. Use the 20.5 mm screws on the front 2 bolts, and the 16.4 mm thumb screws on the back two bolts. Designed to tightly hold the M4 bolts and nuts. Designed in Onshape. Feel free to copy and play with it. (http://bit.ly/2cFxFJz)
