Anet E12: X belt tensioner

thingiverse

I found out after printing MrCrankyface's that the main part wouldn't allow the slider to reach my belt due to the divider wall (end cap). This design removes that wall and provides a better fit for the E12 X-gantry rail. Hardware you will need: 2x - reuse rail mounting hardware 1x - reuse roller bearings and hardware 1x - M4x60mm Hex Socket cap screws 2x - M4 Self-Locking Nylon Insert Hex Lock Nuts 2x - M4 washers 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 roller hardware to place the roller bearings in the slider (don't forget to put the belt around the rollers). 4. Place slider on the guide and insert the screw through the main mount. 5. Slip on the two M4 washers and loosely put the adjustment knob on the screw. 6. Mount the main plate with rail hardware on the end of the X-rail. 7. Adjust the belt tension. If you like this design then you might just like these for the Anet E12. <a href="https://www.thingiverse.com/thing:3163258"><img src="https://cdn.thingiverse.com/renders/37/1d/22/7b/11/3ebfd2ffa6d95a9b6bfdc276ab91a3f9_preview_card.JPG" alt="Anet E12 Two-Piece Cooling Fang" width="25%" height="25%" border="0"> Anet E12 Two-Piece Cooling Fang</a> <a href="https://www.thingiverse.com/thing:3097667"><img src="https://cdn.thingiverse.com/renders/84/82/ac/41/a6/2ed1b627fda92c5bb8c50458bf784eca_preview_card.JPG" alt="Anet E12 legs using current rubber feet" width="25%" height="25%" border="0"> Anet E12 legs using current rubber feet</a> <a href="https://www.thingiverse.com/thing:3114569"><img src="https://cdn.thingiverse.com/renders/f2/66/3e/cb/8f/2ed5c209ebeb59d6e6361c03ec6e9542_preview_card.JPG" alt="Anet E12 make the control unit a part of the printer." width="25%" height="25%" border="0"> Anet E12 make the control unit a part of the printer.</a> <a href="https://www.thingiverse.com/thing:3094220"><img src="https://cdn.thingiverse.com/renders/43/08/66/65/ab/46e583ed1c371ca541d5d76ddaa17db1_preview_card.JPG" width="25%" height="25%" border="0"> To fix the issues with leveling and unwanted bed movements (bed shifting).</a> <a href="https://www.thingiverse.com/thing:3099321"><img src="https://cdn.thingiverse.com/renders/fc/2a/f9/e8/6f/bf75fb7492d2d6d87a3e76a15ac491d0_preview_card.JPG" alt="Anet E12 bracket for SIQUK MK8 Extruder upgrade" width="25%" height="25%" border="0"> Anet E12 bracket for SIQUK MK8 Extruder upgrade</a> <a href="https://www.thingiverse.com/thing:3133492"><img src="https://cdn.thingiverse.com/renders/99/93/ac/bd/f3/867e4b9e261a94fe9ac19a7dfab0ff21_preview_card.JPG" alt="Anet E12; quick lock for the SIQUK MK8 Extruder upgrade" width="25%" height="25%" border="0"> Anet E12; quick lock for the SIQUK MK8 Extruder upgrade</a> <a href="https://www.thingiverse.com/thing:3098952"><img src="https://cdn.thingiverse.com/renders/3e/2f/f4/f9/6d/3aacbaed1e80dae3c102ed225a981025_preview_card.jpg" alt="Anet E12 holders for two Mosfets" width="25%" height="25%" border="0"> Anet E12 holders for two Mosfets</a> <a href="https://www.thingiverse.com/thing:3115835"><img src="https://cdn.thingiverse.com/renders/a0/4e/8a/b6/0e/1492feced056d9ec56b68d42e59b34d8_preview_card.JPG" alt="Anet E12: Cable strain relief for heated bed (improved)" width="25%" height="25%" border="0"> Anet E12: Cable strain relief for heated bed (improved)</a> <a href="https://www.thingiverse.com/thing:3128051"><img src="https://cdn.thingiverse.com/renders/64/5d/2a/fd/b8/bdbf303e1a540d7cc61992c87e53f12a_preview_card.JPG" alt="Anet E12: Y belt tensioner" width="25%" height="25%" border="0"> Anet E12: Y belt tensioner</a>
