This is my first 3D printed prototype ever. It is a minified version of the short GoPro thumbscrew accessory. The model has been created starting from the original one found @ GrabCAD, and has been optimized to allow for a standard M5 hex head screw. This model is on GrabCAD as well.
The prototype has been printed @ FabLab ReggioEmilia using a HP Designjet Color 3D printer.
