A handle for quick release applications using hex bolts

Uploaded stl is for an M10 screw (german DIN931) and you should be able to use it for pretty much other size as well by adapting the dimensions.

The handle has a "freewheeling" function when pulled. You can add a coil spring (see added stl for DIY) to automatically leave the "freewheeling state" -> normally not used if screwed vertically due to gravity.

I am using it for the license plate bar of a boating trailer.

Have fun.
