Low Profile Toe Clamp for CNC Router (Heat-Set Insert Version)

A low profile clamp for securing wood and plastic to a CNC router's wasteboard while still having full access to the top of the stock.

There are two version of this clamp, which differ based on how the the threading is added. This version uses a threaded insert that is pressed in by a soldering iron. The insert has a flange on to prevent it from getting pulled out of place. Compared to the second version, which uses a hex nut, the heat-set insert model can be tightened harder for further clamping force.

The clamp is secured through M5 bolts, and therefore, your wasteboard must have threaded insets (like these: https://amzn.to/2TunKBK)
