Cable chain for Prusa I3 Rework 1.5 by JSuzineau
by Thingiverse
Last crawled date: 4 years, 2 months ago
This thing consist of three parts to use thing:611593 Open Cable Chain for cables between the extruder and the X-motor, and between the X-motor and the Z-motor located by the Arduino board (sorry my identifiers are an awful mix of french and english) :
Support_Chaine_Cable_sur_NEMA17.stl is a ring that fits on the extruder motor with a "end1" connector to the cable chain.
Support_x_motor.stl is a ring that fits on the X-motor with a "end2" connector toward the extruder and a "end1" connector toward the Z-Motor.
Support_Z_Endstop_Z_motor_mount.stl is a remix of my thing:326638 for Prusa I3 Rework 1.0. The 1.5 doen't have the z-endstop but I left it just in case of need.

Support_Chaine_Cable_sur_NEMA17.zip contains the OpenSCAD source files:
M_global.scad: a small general library with shortcuts for translations and rotations and tolerance constant used to ease fittings between pieces printed separately.
vis_M3_5_x_16.scad : a library to integrate wood screws size M3.5 x 16 in designs
M3.scad : a library to integrate M3 nuts and threaded rods in designs.
nema17.scad : a library to integrate nema17 motors in designs

coté_extrudeur subdirectory: the ring for the extruder motor
Support_Chaine_Cable_sur_NEMA17.scad : the file use to generate the ring
Conception.scad : the file used to display in OpenScad a view useful when designing the whole thing (I write the scad files in Lazarus source file editor ).
interne.scad: the main part of the scad code of the thing.

coté_z_endstop subdirectory: to print print this thing easily, it's plit in 2 parts that screw together with two M3.5 x 16 wood screws. The screw shape is defined in vis_M3_5_x_16.scad, eventually you can customize this file if you have different screws.

I designed this thing on a Prusa with a broken and repaired extruder which is shifted 7 mm towards negative Y (i.e. toward the front) relatively to the original one.
May be you'll need to tune the scad files, especially in coté_extrudeur/interne.scad line 19 by changing " tx() " by something like " tx(7) "to shift the chain connector towards the front of the printer.
But the other ring on the X-motor can slide freely a few mm in this direction so there are good chances you won't need to do this tuning.(update 2017 October 12th: it's ok with an original extruder)
For the future I'm considering to rotate some degrees toward the front the connectors for the chain between the extruder and the X-Motor because as you can see on the pictures, the chain can hit the spool holder or the LCD-screen when printing something higher than approximately 90 mm.
