Thumb Screw for Bibo2 Printer Bed

Here is a thumb screw to replace the stock wingnuts for leveling the Bibo2 printer bed. These are 30mm OD, which just clears the support frame on my printer. They hold a 3mm nut inside a recess, which you will need to provide, but are designed to work with the stock leveling screws. The larger diameter and full perimeter make it much easier to fine tune the leveling adjustments.

EDIT: CAUTION - the front right wheel might hit the LCD screen housing as the table lowers. I will make a smaller wheel. But in the mean time, please caustiously check your clearance.
