CNC table clamps / hold downs

This is a 3D printable version of Marius Hornberger's excellent Ultimate Worktable Clamps system: https://www.youtube.com/watch?v=O-rqf4uSXRE&t=161s

There are 3 versions depending on whether you have 15mm, 22mm, or M6 holes in your waste board.

You need to print two handles of the correct size, two spacers of the same size, and two clamp blocks.

This is suitable for hole spacings of around 75mm to 100mm

Print with very high infill and 5 perimiters for strength.
