When soldering, PCB needs to be held tightly . (when desoldering for example)

This pcb holder can be clamped on the desk, and hold your pcb firmly. The grip plates' interval can be adjusted up to 60mm.

Update (25.07.06) : Modified to utilize the Universal Modular Clamp (v2)

This model is an attachment for my Universal Modular Clamp. Print the clamp from the link!

Assembly Guide : 

• Assemble the attachment with the clamp printed from the link.
• Refer to the description page of the clamp for details about attachment securing.

• Keep one of the pcb-grip-plates remaining on the unthreaded area of the bolt. Screw/unscrew the bolt along another pcb-grip-plate to adjust an interval.
