3 Points leveling bed support (Q744177)

Tired of the four point difficult to adjust, I design very simple parts to be use with 12mm Diameter aluminium RC Heli Tail Boom. I use also a carbon fiber plate 1.5mm thick so the entire bed is very light and rigid. It is made to work with 10mm rod (LM10UU) and a Trapezoidal screw 1mm pitch My machine is an H-Bot derivated from a Sakura Cube. The lenght of the aluminium tube is 235mm, so you can get one lenght of 500mm for 1.99$.
