SainSmart Genmitsu 3018 Drag Chain Upgrade

thingiverse

Designed a mount to be screwed on to the Z-axis motor to accept a 10x20 drag chain. You will need __4 x M3 threaded brass inserts__ and __4 x M3x10 screws__ to finish the assembly. I made some holes to loop zip ties for cable management - I later found out that they were too many. You'll just need to use the one directly at the motor. I recommend putting in the zip tie first, before attaching the mount to the Z-motor. I used a spare __M3 T-nut__ and __M3x10 screw__ (included in the 3018 kit) to attach the drag chain to the X/Z axis. Because it's only one screw at that end, I designed a little support bracket which should snap fit around the drag chain on the the 20x20 aluminium extrusion. __FIY:__ The covers for the aluminium extrusion which you see in the background are from here: https://www.thingiverse.com/thing:2523427 Great fit, props to the designer! *Pro tip: Use the 100mm version and scale it to 145% on the X-axis only. That way you will end up with a 145mm piece. Two of those will go perfectly into the 290mm aluminium extrusion of the Y-axis.* Repeat with different multipliers to get perfect lengths for all your extrusions!
