Anet E12: Y belt tensioner

thingiverse

I had trouble printing MrCrankyface's design for my E12. I decided to change it into a two-part assembly so each part could be printed for layer strength. You will need the following hardware: 1x - M4x60mm Hex Socket cap screws 2x - M4 Self-Locking Nylon Insert Hex Lock Nuts 2x - M4 washers 2x - M3x15mm Hex Socket cap screws 1x - M3x30mm Hex Socket cap screw. 2x - M3 Self-Locking Nylon Insert Hex Lock Nut 1x - rail mounting screw and t-nut. To assemble the design, follow these steps: 1. Press fit the M4 locking nuts into the slider and adjuster knob. 2. Screw in the M4 60mm screw into the slider and tighten. 3. Use the M3x30mm screw and locking nut to place the roller bearings in the slider (don't forget to put the belt around the rollers). 4. Mount the main plate with rail hardware. (make sure to center between Y-rails) 5. Mount the guide part of the mount with the two M3x15mm screws, these will cut their own threads, these are just to keep this piece aligned and in place. 6. Place slider on the guide and insert the screw through the main mount. 7. Install the two M4 washers and knob on the screw and adjust the tension on the belt.
