K40 Drag Chain
thingiverse
Got a K40 laser cutter. I wanted a drag chain for my air and red dot laser. Well none fit my needs. Also my laser cutter happens to have a door hinge which doesnt allow for other chain setups. SO i design this. Made it with the ability to easy remove if needed to. Also didnt want to drill a mount hole so close to the tube. So made a mount that uses a hole always there. I printed 36-38 chain links. 1 end and mount. Takes m3 screw. The rear mount i believe i used 6 or 8mm For the carriage i used one m3 8mm For the chain to carriage roller one m3 20mm and 1 m3 nut **update** I had the chain move to close to the laser path in the top upper right. So did a little re design and added a stopper. *chain link file added. Sorry it was missing
