Description
Cable Chain Setup for Prusa Mini and Mini+ x-axis motor and the heatbed.
Updated
X-Axis chain can now mount on the front or side of the Aluminum extrusion!
This has some other prints remixed in it.

The default heatbed cover from Prusa
Update
As per a request I've added modified parts 01A and 02A for mounting the chain on the lower side of the Aluminum extrusion instead of the lower front. This should give enough clearance for a brace on the front. These are also connected with a nut and bolt rather than a ziptie. See pictures for reference.
NOTE
I have not physically tested the side mount parts as i have a handle on the side of mine, but it still may work if its mounted just above the handle.
Update 2
Added headbed clip for Mini+, notes at bottom of instructions.
Additional Parts:
3 - Small Zipties
3 - m3*10 Bolts
3 - m3 nuts
Edit
1 More Nut and Bolt if you chose the side mount option.
Print one each of either 1 and 2 (Front mount) or 1A and 2A(Side Mount)
Print one each of parts 3-8
23 - part 9 for the x axis
25 - part 10 for the x axis
15 - part 9 for the Heatbed
16 - part 10 for the Heatbed
1 of parts 7 or 7a depending on mini or mini+
PLA or PETG work great.
0.20 Layer height.
15% infill.
No support needed.
All parts are pre-oriented for printing.
X-AXIS:
Remove electronics covers on the MINI and reroute x-axis wires under the frame. Slight cutting away of the electronics case will probably be necessary for cleanest look.
Place 2 nuts (or 3 if using side mount version) 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, slide into bottom of z-axis frame, on front or side depending on which parts 1 and 2 you chose, loosely bolt part 4 and route cable through.
Add x-axis Chain and clip parts starting from the motor side.
Tighten bolt on part 4.
HEATBED:
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.
Update: MINI+
The MINI+ has a different rear plate that part 7 does not fit. I do not have a MINI+ to test but I've added part 7a that works. Thanks to jcarland for noticing it and Hanes244, CFXS, HexDriver for testing!
For best fitting, a hole will need to be drilled into the electronics case next to where part 7a sits to route the heatbed cables. Part 7a should then cover the hole.
Update 2: Mini+
Added a new part 7b which is a very low profile version that may work better for some.
“CAUTION”
Be careful not to damage the control board when drilling! The board may need to be removed for safest drilling.
Some finagling may be necessary to get the cable length correct.
Attach part 7a mount to frame with the y-axis motor cables between the mount and the frame.
Reconnect heatbed and replace electronics cover.
*Note:
The files for the x-axis are mis-labeled z-axis and I'm currently too lazy to rename and reupload them;)
