About this 3D model
This is my rework of this thing (https://www.thingiverse.com/thing:1959208) personally i think sometimes people over think things when it comes to 3D printing, the original author did a great job with the original part but they were focused on using the original hardware to a "T" instead for strength i changed the parts over to directly accept 12mm long 3MM screws no nut needed. the part is stronger and works in PLA. enjoy -T Anet A8 Y Belt Tensioner by tbillion is licensed under the Creative Commons - Attribution - Share Alike license.
