Optamus Prime

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.
An imaginative replica of Optimus Prime symbol. This is a special and unique piece that will add to your collection of Transformer pieces.
