PCB clamp for CNC machine

When you're into DIY electronics and you want to create your own PCBs with your CNC machine, you need the right clamps that keep the PCB level and protect your T-slot bed from being drilled into. I created these on the basis of ideas I got from Youtube to protect your T-slot bed in this way. The clamps slide through the slots on your T-slot bed. Depending on the margin and the settings on your printer, this may be a tight fit, nothing that a bit of sanding cannot solve.

Additional components

You only need 4 hex bolts M5x16, 4 M5 washers, and 4 M5 T-nuts. If you got a CNC3018 or similar from E-bay or any other e-commerce company, chances are they're already included. The bolts can be pushed into the knobs with some gentle persuasion of a hammer, if necessary you can add some glue.

Print settings

Nothing special, I used PLA, 0.2 layer thickness, 25% fill and 2 walls. There is not going to be a whole lot of tension on the clamps.
