(remix 2021) Prusa Mini Cable Chains (x-axis, headbed)
Description
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_Lower_Mount V2.stl (stronger attachment to both: chain and vertical profile) 2) 01_-_x-axis_Motor_Mount_p2 V2.stl (shorted 2mm, it was touching vertical rail) 3) 06_-_heatbed_Cover V2.stl 06_-_heatbed_Cover 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. Prusa i3 MK3 Cable Chain Add-on (ALL AXIS) https://www.thingiverse.com/thing:2862375 X Stepper sleeve wire clamp https://www.prusaprinters.org/prints/3436-x-stepper-sleeve-wire-clamp The default heatbed cover from Prusa 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.
