K40 Drag Chain Kit

thingiverse

Update: Added a version that's 3/8s taller, addressing issues with laser beam hit. Mine was due to using stiff hose instead of recommended soft silicon type. My remix includes a New Designed Carriage Bracket for easy installation and minimal use of carriage screws on the plastic. I modified my machine for maximum rear travel, incorporating this bracket and its height plus chain mount location to prevent chain bunching and pressure on the gantry/carriage/laser head. This keeps forces centered, preventing carriage play in wheels from uneven forces. Simply slide it on and place one carriage plate screw into the slot, tightening it without removing or realigning your red dot if you have one like mine.
