Revised X-Axis (Prusa I3)

thingiverse

**IMPORTANT:** Because Thingiverse changed things and for some reason broke the markdown formatting, the parts list and some other crucial details aren't properly displayed. I will try to fix this issue, but in the meantime please consult this collection for compatible x-carriages https://www.thingiverse.com/vekoj/collections/revised-x-axis-prusa-i3. And dont hesitate to write a comment/message me for further clarification if needed. The revised X-Axis is fully compatible with stock Prusa frame (MK2/MK3), as well as with the Haribo/Zaribo/Bear frames. **The compatibility with different extruders comes from the X-carriages provided in this listing, stock ones will NOT work, unless explicitly stated otherwise in the compatibility list below / please check the compatible X-carriages in the description.** The design is intended as an upgrade to the stock one Prusa Research provides, adding features like: * **Belt tensioner** - A simple and sturdy system for fine adjusting the belt tension on the X axis while keeping the correct belt path. Replaces the stock design of rotating the X-motor which stresses the X-end printed part, in some cases, to the point of breaking. * **Belt tensioner "puck" customization** - Allows the use of different hardware (idlers) with the existing printed parts (whichever option you went with). You can pick the corresponding tensioner (puck) with the idler you have available, and even switch later on just by printing another version of the puck without the need of changing anything else in the system. The tensioner pucks are interchangeable. * **Bearing clamps** - Allows a lot more easier assembly of the X-ends, replacing the stock pressure fit design which can be inconsistent with different materials/printer settings. The clamps additionally allow some pre-tension on the bearings, but please do it with caution as you can cause the bearings to bind. * Unified and customizable system, compatible with plenty of available extruders for the I3 and the clones alike **(\*with compatible X-carriages included in this listing, stock ones will NOT work, unless explicitly stated otherwise in the compatibility list below / please check the compatible X-carriages in the description)**. Each feature of the 3D models was carefully checked and fine tuned. Optimized for FDM 0.2mm layer height printing, making sure the parts are accurate and easy to print. --- For detailed instructions on how to fine tune your X-axis while assembling, please check out Bear Upgrade excellent guide [here](https://guides.bear-lab.com/Guide/5.+Final+adjustments+and+calibration/5?lang=en) --- STEP files are included for your modding pleasure and convenience.
