UPDATE:8/9 added a bowden guide so filament enters extruder straighter. was having issues with loading new filament where it wouldn't be grabbed. 

UPDATE:

Made the nut thicker so doesn't slip as easy. slap a zip tie on it once snug

Update: Added a guide for rear right screw on top of machine that would catch chain now and then, particularly if used in conjunction with acrylic top (see pic)

Update: Gave the print head mount some extra… thiccness

Mounts for cable chain. 

Toolhead;

Remove extruder cover and extruder. Loosely attach tool head mount. re-attach extruder. Tighten everything down.

Frame:

Remove old grommet. Mine is still on the cable bundle inside the machine incase I(for an unknown reason) want to put it back. Gently flex split nut around cables on the underside. Fit cables through mount on top side. Screw together. The top mount is pinned. Snug the nut. Too tight and it will slip. just has to be snug.

I used this cable chain 

The five or six links closest to the toolhead need to go the opposite direction.
