Anet a8 Butter slider X carriage for e3dv6 with built in 8mm bearings for Tech2c Mount and endstop

thingiverse

After installing PLA printed LM8UU bearings on the Prusa i3 rework by Emotion Techs' X carriage, I discovered that the X carriage wasn't fitting correctly. My printer's dimensions were off by about 0.5mm from the design specifications. If you've ordered an Anet recently (after February 2017) and are experiencing similar issues, this modification is a game-changer. The bearing slides smoothly without any need for zipties. Check your space between the rails with a caliper; my measurement was around 54mm, which I'm sure falls within a tolerance of 0.1mm, meaning 54.1mm or 53.9mm should work on your Anet. To print this modification, print it on its side due to the bearing holes' tendency to warp if printed flat. If you're unsure whether the part will fit, you can print around 10% of the design and then stop it. Remove the rails and test the X carriage for a proper fit. Refer to my photos for reference. If you need to file the bearing holes slightly to achieve a perfect fit, be cautious not to overdo it, as it's almost a precise fit already. I also made changes to the screws to work with M3 screws, allowing them to screw in from the front with an M3 nut at the back. Don't forget to oil your rails and print with the endstop touching the build plate. When installing the M3 nut, use the heat method to press it in. UPDATE: I've also uploaded my hotend mount and blower fan version on Thingiverse (http://www.thingiverse.com/thing:2162732) and YouTube (https://youtu.be/fCvlAIAdF4g). Enjoy printing!
