Belt clamp for H1 plastic bed (original h1 table)

My H1 arrived without a belt clamp for y-axis belt. This clamp fit better and fix the belt without high screw pressure.

With this design, you can adjust half tooth of belt pression, if you need it, only inverting the position of the clamp.

I still added a openscad parametric version of this clamp, it is good change the parameters for different belt sizes.
