A8 X-axis Tensioner (remix^3)

thingiverse

I was using my own remix of the Anet A8 X-axis tensioner rod and it failed miserably. As seen in the photos, the part was severely compromised where the material was incredibly thin around the hex nut recess. This design attempts to fix this issue in two bold ways. First, extra material is added to the idler pulley fork, making it a whopping 2mm taller than before. Second, I've split the design into two separate pieces so that we don't rely on the adhesion between layers for the strength in the direction we're trying to provide tension. Use M3 nuts in each slot in the body and an 18mm M3 bolt to attach the head firmly to the body with confidence. The body piece is symmetric, either end can be used for the head without any issues. Re-use the original M3 nut (which I upgraded to a lock nut) and M3 hex key bolt for the idler pulley to keep everything in place. Use the back plate from kennethjiang's original thing to complete the design. https://tinkercad.com/things/jOsiyrw8EmL https://tinkercad.com/things/1fgagktT60D Print Settings: Printer: Anet A8 Rafts: Doesn't Matter at all Supports: No supports needed whatsoever Resolution: 0.4mm nozzle, 0.2mm layer for optimal results Infill: 100% head, 40% body for added strength and durability Notes: Print with a 1.6mm top/bottom/shell, which is equivalent to 4-layers for best results.
