Single Motor, Dual Z-Axis, Mount & Spacer for CR-10/Ender 3

cults3d

This is a collection of remixed parts for a belt-driven, dual Z-axis, upgrade for the Ender 3/CR-10. Use the projects linked and replace parts from those projects with the ones available here. Spacers I found the inner diameter of spacers provided by "Dual Z axis lead screw mount ender 3 , probably fits cr-10" (3Dthingsmaker) were too tight. I redesigned it with a higher polycount and a slightly larger internal diameter. Motor Mount I wanted to use the "Ender 3 Dual Z-Axis Mod with Braces" provided by danielfmo and also the adjustable "1310mm belt stepper mount" by ryedesign. However, the motor mount was designed to work with the parts in "CR-10 Dual Z with top mounted stepper". As a result, the motor mount sat too low. I have redesigned it, adding some height, so it aligns with the GT2 pulleys on the leadscrews. Leadscrew Nut Mount The remixed mount "Dual Z axis lead screw mount ender 3" provided by sudiik is a good improvement and fixes some bad geometry from the original, however, I felt the internal walls for adding strength aren't necessary as this can be achieved with more infill. Also, I found the thin walls in the middle between the centre hole and the bolt holes easily crack under any kind of strain. I have attempted to introduce more material in hopes of making them stronger. Print on side, as shown in pictures above, to ensure a strong part. Spool Holder Adapter Due to the belt path colliding with the stock Ender 3 spool holder, I have modelled an adapter that will raise the spool holder up out of the way. Top Bearing Mount Need 2 of these. It is a remix of the version provided by danielfmo "Ender 3 Dual Z-Axis Mod with Braces". The brace part of it has been removed, since I don't intend on using it, and the entire geometry has been recreated as I found a lot of non-perpendicular faces and other anomalies. The holes that mount to the aluminium extrusion have been enlarged to make it easier to use M5 bolts without the need to drill out holes. This part does not need any support. Print with 40% infill. The model has been pre-oriented for printing.
