Downforce clamps

These are two different versions of my downforce clamps.
They use a clamp angle of 45° to split the clamping force in two directions (in and down).
Check out this Animation!

Version one is for mounting on one rail only.
Version two is designed for two rails (40mm apart). 
I made the version 2 especially for my Spoil and Mounting Board for CNC (feel free to check that out as well).

Choose the version you like and print base + head.

Material list:

• For mounting base + head of a clamp together:
