https://www.thingiverse.com/thing:4441076 presented a thumb screw to replace the wing nut on the front-left corner of the BIBO bed. It is too wide for the other two positions.
I have created a smaller version to fit the right-front corner and the back-center.

A M3-.50 nut is required.

uphillian: I extended the indent to accommodate the longer bump on the 20V MAX tools.
I had larger magnets on hand, so I replaced the two smaller holes with one large one.
