CNC hold-down clamps

Here are clamps that will firmly secure the workpiece to be machined on your CNC's spoilboard. I made them with four different lengths because I noticed that at times there was a slight missing millimeter between the workpiece, the clamp, and the spoilboard screw. Either it was too far, or there wasn't enough space. Now the problem is solved

The sides are slightly higher for better reinforcement during tightening but remain flexible enough not to break during this process

A little extra, it also features an indication for the panel thickness it is intended for, as well as a different color depending on the thickness. This greatly facilitates finding the right clamp

It is printed in PLA but can be made in PETG
