Summary

This is a Nut Tensioner for M5 nuts.
My used nuts are 7.85mm wide and 4mm high.
The Tensioner is 26mm wide and 10mm high.
Best Time to insert the Nuts: directly after print!

I use it to get the my screws of the Boxes in my Camping-Caddy in the right position because its also hard to get there with "normal" Tools.

Notes:                    

PLA printed
 

Infill is required at min. 40% to get it strong enough!
