Trigrips Work Holder

This is my version of a handy workpiece holder for woodworking.
The idea is add non-slip foam to the flat sides and base to prevent it slipping. The spike on top offers a tiny point of contact when painting a workpiece.

This version is 40mm wide at the base and 20mm thick. I will probably experiment at some point with different sizes and will share when ready.
