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.

Notes:
looks like it has hinges in the photos but it doesnt, i used a piece of tap to make the top hinge on the bottom, top fits quite loose on the bottom part so u might increase the size of the base to 101% just to snug it u a little. i may update it with little dots to give the cover something to grab an hold in place. its fine the way it is just becareful not to try to pick it up with the top cause it could cause u to drop the bottom an its not fun trying to find 50 button cell batterys that u just dropped.
