Laser Honeycomb Bed Clamp

thingiverse

I use 3mm and 5mm plywood on my laser with honeycomb bed, and these hold the edges down perfectly. Just push them in and lean them forward. When done, simply press the wood down a bit and they pop right out. I cut mine out of 5mm plywood, and they work great. You could also import the .svg file into your favorite 3D program, extend them by about 5mm and 3D print them, but in the time it takes you to do that, you could cut a thousand of these from plywood.
