There are other versions of this floating around however the chain bows forward when all axis' are zeroed. Also this exits the head cable before the top mount to avoid unnecessary stress on it. Pretty straight forward to print and install. This uses a 10x20 cable chain.
You'll need some T-nuts for the chain stop, I've used M4 nuts and bolts but M3 will work with washers. 4x 15mm M3 and washers for the top mount.
