About this 3D model

This mounts ontop of the 2020 and just supports the cable chain that seem to sag down and sometimes hits the stepper motor pulleys which can cause all types of issues. The longer side of the two arms goes on the inside. I have printed and installed and can confirm it does not interfere with the hotend mount. Supports are needed but you only need to set it to "build plate only" if using cura. If doing manual supports you only need a few supports on either side and a little bridging will do the rest. UPDATE: 15/08/2018 I added a longer/taller version which is 9mm taller than the original. It gives abit more clearance from the pulleys, especially as the drag chain keeps getting heavier when adding more wiring.
