Cable chain for 2020 Aluminum variants of the Prusa i3. I made this for my Folger Tech 2020 Prusa i3. I used ABS because the aluminum bed gets pretty hot during long ABS prints. If you only use PLA or no Heated bed, PLA is probably fine.
See instructions for printing frame mount.
I have revised the design a couple of times and finally have it in what I believe is the best configuration. Obviously printing a new belt mount for the Y axis belt would be best, but I didnt feel like completely taking apart my Y axis again.
The chain was confined to too small of an area and would occasionally snag on the bearing holders on the right side. So I made an offset mount , as well as the same offset + 6mm more.
The +6mm offset link goes under the bed, and the other offset goes on the frame mount. I alsmo moved my frame mount outside of the Y rods. So with the added offset the chain now clears the bearings completely and there is no more snagging and breaking links. Enjoy!
To print the frame mount, rotate it so that the clips for the chain are facing straight up. So the edge of the part touching the bed forms an L. I also printed it with a brim in ABS.
