Description

PDF

The cnc clamps here were designed in order to get the biggest possible working area for three different PCB dimensions: 70x50, 100x70 and 120x80 (mm).

For good results: clamps should be mounted as symmetric as possible (with respect to board outline) and tightened from left to right or from middle axis to outside.

In the images shown: pcb clamp 14 (light grey), pcb clamp 19 (red), pcb clamp 24 (black) and pcb clamp 32 (yellow).

Printed with PETG, 4 perimeters and 40% infill.
