FORMAL release of my previous Thing: https://www.thingiverse.com/thing:2794755
I've updated the heatbed top and heatbed chain link to include an angle that should help the y-chain clear the zipties & back of the frame.
Finally, after many promises, I've included an Einsy case that can be used with a Rpi Zero mounted to the Einsy headers (einsy-mount-cable-chain_rpi0_addon). This was based 100% on fritte2000's beautiful design here:https://www.thingiverse.com/thing:2886648 (love the screwless approach). You will have to print the cover from fritte2000's page.
Disclaimer #1: I literally just finished this design and haven't been able to test it yet. I'm 86% confident it'll work, but no promises. I don't have plans to use an RPi0 so any test prints with feedback would be much appreciated.
Dislcaimer #2: With the RPi0 Einsy case, you have to use the newly updated z-chain and applicable components:
- z-chain-motor mount_A
Disclaimer #3: If you want to use the newly updated z-chain links (from disclaimer above) without the RPi0 case, I also updated the original Einsy case to be compatible with the new chain design.
Disclaimer #4: Noticed I didn't update with a pass/fail on the updated flat-bottomed v-groove version of the extruder back. It passed. Old comment deleted.
This is a cable chain add-on to replace the spiral wraps or cable braids on your Prusa i3 MK3. No modifications needed other than trimming the filament inside the cable bundles.
Quick note on the screenshots, I only included the "main" chain due to SolidWorks repeatedly crashing with all 3 axis chains involved. Guess I need to upgrade my home workstation :(
Inspired and remixed from the following designs:
- Prusa i3 MK2S No Mod Cable Chain Kit - All Axis by SoundDoc
- Prusa i3 MK3 X carriage back plate with belt access by jltx
- Cable chain upgrade for Prusa MK3 by sodamaexchen
- Prusa i3 MK3 SolidWorks Assembly (with STEP) by jzkmath
All parts printed with PRILINE PETG with the following settings:
- .15 for z-axis_chain_clip_revA.STL and z-axis_link_revA.STL
- .20 for all remaining parts
- Recommended Supports
- Supports from build-plate only:
- 100% for all cable link and clip parts
- 20% for remaining parts
- Nozzle: 245 first layer, 242 remaining layers
- Bed: 90 for all layers
Bill of Materials
For the following BOMs I am only including hardware that is not already installed on a standard MK3 assembly. If needed, please see screenshots for assembly aids. Everything self-explanatory assembly-wise, but if you run into any issues please comment.
Einsy & RPi3 (Optional)
(x1) rpi3_swing_case_revA.STL (optional)
(x2) Pi_Hinge_revA.STL (optional)
(x2) Pi_Hinge2_revA.STL (optional)
The following hardware is only needed if you are using the RPi3 add-on. Otherwise the Einsy mount is simply swapped out
(x4) M3x10 SHCS
(x1) M3x8 SHCS
(x4) M3 hex nut
(x1) M3 square nut
(x4) M2x8 SHCS
(x4) M2 hex nut
(as needed) trim Ø3mm filament
(x2) M3x10 SHCS
(x2) M3 hex nut
- Update print information to include recommended supports
- Part designs not updated, but I reoriented the STLs to how I printed them
Updated following parts due to not fully enclosing on the lower x-axis bearing (new revision level A-02 included in STL filename):
- Added .zip folder of SolidWorks models of my current Prusa MK3 assembly
