Remix of https://www.prusaprinters.org/prints/27742. I needed a compact solution for the X-arm chain because my printer sits in a very tight space.
The heatbed part worked perfectly for me and is unchanged.
Remove electronics covers on the MINI and reroute x-axis wires under the Z extrusion. I had to cut a little the electronic box to achieve that.
Place 3 nuts into part 1.
Ziptie part 1 to the x-axis motor.
Bolt part 3 to part 1 with the cable between them.
Place part 2 against part 1, route cable and ziptie part 2 and cable to part 1.
Place nut in t-nut, loosely bolt part 4 to T-nut. slide into side channel of z-axis extrusion, towards the control panel, above midway.
Route Z-axis wires in the channel ( i removed the black wrapping around the cables ) and cover them with part 11 that clips in the slot below part 4. slide part 4 downwards against part 11, tighten screw.
Add x-axis Chain and clip parts starting from the motor side. Tighten
(copied from the original design.)
Replace bed cover with part 6.
Unplug heatbed wires and reroute through y-axis wire hole.
Add 15 chain and clip pieces starting from the headbed side.
Place part 8 Adapter on heatbed cables and snap into part 7
Mount with the adapter open end Up. Some finagling may be necessary to get the cable length correct.
Attach part 7 mount to frame with the y-axis motor cables between the mount and the frame.
Reconnect heatbed and replace electronics cover.
