Anycubic i3 MEGA Chains

thingiverse

Updated. The Z chains look a bit rough but are functional. There are 14 links on each side. Pictured fully extended with all links down. 10mm clips on left, 7mm on right. The top Z connectors snap into the holes under the carriages. They fit somewhat tight, requiring a screw and nut through the hole in some cases. This set of chains is for X and Y axes. I initially used junaling links but replaced them with snap-in retainer clips. It's still compatible with those links though. Installation is relatively easy (if you can find screws to fit the carriage and base), but all parts except clips were printed with supports and brims due to added slots for clips and brackets, requiring a lot of work to remove excess plastic. The X chain uses extra screw holes on top of the carriage, while the base connector uses holes next to the cable, facing the back. The first link off the bed is flipped to hold the chain low. There's an extra reversible link not used. There are 19 links on X and 14 on Y. The 10mm clip was used for X and 7mm for Y. To ensure smooth movement, slide the bed forward and backward with the carriage all the way right, avoiding any contact with the leveling knob or reaching the full range. Edit: Z_topRight is actually the bottom swivel link for both sides.
