I just added Benchy. (And I scaled the model up--so if you want it super tiny again you will need to scale it down in your slicer) This is just modified of the completed file in the zip.

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.
