Anet A8/AM8 2020 X-Axis Conversion

I combined the x-axis rod holder with the motor mount and the belt tensioner, resulting in a reduced width for the printer. You will need a 430mm 2020 V-slot extrusion instead of the original 500mm to accomplish this. I remixed it from another design and now it's even more efficient. On reflection, I strongly advise using the "long" version with two bearings at each side. **Updated: February 10, 2019** I have uploaded the source files in SketchUp for your reference. **Updated (Parts List): July 20, 2018** Here is a list of non-printed parts you will need: - 1x 430mm 2020 V-slot Extrusion - 1x GT2 20-tooth Idler wheel (depending on the bore - 3mm or 5mm - print the equivalent X-Belt Tensioner part) - 1x 20mm screw for securing the idler wheel (either M3 or M5 depending on the idler wheel bore) - 1x nut for securing the aforementioned screw (either M3 or M5 depending on the idler wheel bore) - 1x 20mm M3 screw for tensioning the belt - 1x M3 Nut for the aforementioned screw **Updated: February 8, 2018** I have created short and long versions of the carriage using one or two bearings. The long version extends downwards without affecting the maximum print height. Additionally, I designed versions without endstops; if you need an endstop, you can use this one from Thingiverse: https://www.thingiverse.com/thing:2439194 Lastly, the design includes "anti-wobble" protection for the Z Axis. The holes for the lead screw nuts and their mounting screws are larger than needed to accommodate tightening the screws just enough so that the nut can move freely on the horizontal but be steady on the vertical. This setup absorbs the wobble of the leadscrew, ensuring stability during printing. Be sure to use locknuts as normal nuts may unscrew themselves from vibrations over time. To reduce friction further, I used shims: https://www.thingiverse.com/thing:2216161 printed in PLA. Here's a small video demo of the anti-wobble feature: https://www.youtube.com/watch?v=_BI2iKsqJhs **Updated: March 17, 2018** I added an x-axis belt tensioner version for an idler pulley with a 5mm axis. **Update: April 4, 2018** The E3D mount in the photos is my design (or rather a remix of a couple of designs I liked): https://www.thingiverse.com/thing:2791211
