Over centre quick release clip

I designed this for my lawnmower that has handles which have to be loosened every time it is put away. The idea is that instead of unscrewing the nuts that hold the handles together you just release a clip. No unscrewing. 

Much faster to put away the old beast and reassemble it every time I want to use it.  

The application could extend to any bolt that needs doing up and undoing regularly. EG the bolts that hold down a tool holder.

This clip is for an M8 Nut and bolt. The M8 (13mm AF) nut fits into the plug. The plug then is inserted into the circular hole in the handle.

The GCODE is for an .8mm nozzle and a volcano head which is really too big for this detail (if only I had another Prusa with a .4mm nozzle!) So re-slice the .stl s with your preferred settings.
