brock 2020 clamping strain relief for 30x40 Laser Engraver CNC

thingiverse

This cable clamp snaps onto the 2020 channel, holding power and USB cables securely in place to prevent stress at the control board. The DIY laser cnc/engraver sold out of China as the "30x40 CNC Laser Engraver" lacks a built-in cable management system, but it's an excellent hobby tool for its price, with many upgrade possibilities. This wire holder prevents damage to the control board by holding wires firmly in place during movement. A small hole in the center allows a M3 (or 6-32) screw to secure the holder tightly. As part of a series of upgrades and enhancements to the 2020-based 30x40 CNC Laser Engraver, I'm posting all these designs now and will add links shortly.
