Ender 3 Pro Y Axis Linear Rail Upgrade

thingiverse

This is a test to convert the Y axis of my Ender 3 Pro to linear rail. For this, I used two MGN12H 300mm Linear Rails, some screws, and a small amount of ASA filament. To fit the linear rails correctly, I made a tool: https://www.thingiverse.com/thing:4242580 I used four M3 screws with T-Nut on each side. The brackets are required twice and are attached to the guide with four M3 screws each. The Y Endstop is attached to the side of the limit switch with an M4 screw. Now you can mount the carriage with four M5 Screws on top. That's it, thanks for reading! Maybe I'll also create a version with M5 Inserts. At this moment, it works fine with the thread printed in ASA. Let me know what you think or if you have any improvements. This is just a test to see if linear rails make an improvement for me. Whether they do depends on the quality of the linear rails used. My curiosity is partially satisfied.
