Clips to secure wood or paper to Snapmaker laser work surface

The clips will push into the aluminum work surface used on the Snapmaker machine when set up for work with laser. One side pushes against thick work, the other will hold down paper or cardboard. I found the rubber pieces that Snapmaker provided too difficult to position accurately. There are 2 files included one is thicker than the other for lager work like wood. The best thing is that if the laser cuts one be accident, just print another.
