Summary

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.

I redid it and it is now working well.
This is for the General Tools dovetailer

How I Designed This

I designed this with ThinkerCad in order to replace a broken piece in my dovetailer.
