(remix 2021) Prusa Mini Cable Chains (x-axis, headbed) by vasilyd

Last crawled date: 3 years ago

I'm very greatfull to @Autotilt for the original model.
Thus, while printing and assembling thin parts broke (heatbed mount, x-axis low mount, x-axis upper mount). I improved those, the present remix is FULL. It includes some orig.parts and new if needed (marked with names xxx_V2.stl).
Improvements
1) 04_-_x-axis_LowerMount V2.stl (stronger attachment to both: chain and vertical profile)
2) 01-_x-axis_Motor_Mountp2 V2.stl (shorted 2mm, it was touching vertical rail)
3) 06-_heatbedCover V2.stl 06-_heatbedCover V2.stl (stronger attachment to the chain)
4) 07-_heatbed_Mount V2.stl (stronger attachment to the chain)
5) updated printing instructions
6) added 1 more chain-parts into each axis, it is bending nicer on the extreme extension
7) I include .3mf files for Prusa Mini (it includes sequential printing)
8) changed orig filenames from z-axis to corrent x-axis :))))
Cable Chain Setup for Prusa Mini x-axis and the heatbed.
This has some other prints remixed in it.

Print Instructions
Additional Parts:
3 - Small Zipties
3 - m3*10 Bolts
3 - m3 nuts
Print one each of parts 1-8
24 each - part 9 for the x axis
25 each - part 10 for the x axis
16 each - part 9 for the Heatbed
17 each - part 10 for the Heatbed
(Advice: print few more part-10 elements - they break easily while assembled)
PLA or PETG work great.
0.20 Layer height.
15% infill.
No support needed
All parts are pre-oriented for printing.
sequential prints (see attached .3mf files)
IMPORTANT: print chain elements (part-10) into 10 pcs batches, and than sequentially. If print all 40 pcs they warping and detaching from the table - you loose very long print.
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 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 x-axis frame, 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.
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.
