On the CNC side of life I'm just a low level hobbyist...
I tried several things ...
a fan
some molds for my RC planes
SOme RC Planes from block EPP
a handle for a knife
a knife itself
rc plane retracts

and actually thinking about to make molds for that Me410

Also use the gantry router in modified way as a hot wire cutter
