Anet VM8 Project 2020 Frame

thingiverse

This project was inspired by my desire for a robust AM8 frame to replace my trusty, well-modified Anet A8. Unfortunately, I couldn't justify the cost of 4020 extrusion, which currently costs £70 or more. I priced 2020 extrusion on AliExpress and was amazed that three 1-meter lengths could be obtained for just £20. Two weeks later, my shipment arrived, but I had already begun working on my project, remixing, measuring, and printing the necessary parts. Most of the inspiration and components came from Venom V2 3D printer and Pheneeny's AM8, to which I extend my gratitude to the primary sources. Although I appreciated venomprinting's design, I was unable to resolve some measurements and design issues. I designed a new Y belt tensioner based on Venom V2 combined with AM8 to allow for adjustments. I also remixed Venom V2 Y Motor mount to fit inside the frame of AM8 style. **Parts List** Anet A8 component parts **2020 Aluminum Extrusion** 2 x 360mm (Optional drill a 4mm hole in each, 140mm from rear, 90deg through center) Note: Please check your y-axis rod lengths as they may be up to 3mm longer.
