An Anet A8 y-tensioner kit for a 2017 printer with 8x8mm holes and spaced 12mm in z-axis. Remixed from the sources mentioned below and with the following features:


  • Separate left and right "arms" to print without support
  • Left and right arms with small inset and outset so that the pulley spins freely
  • Fits tight and don't bends when tightening the bolt
  • Fixed some non-manifold pieces to improve slicing in Slic3r 1.3

Resolution and infill by piece:
Pulley, the most critical: 0.1mm, 100% infill
Bolt and plate: 0.2mm, >= 20% infill
Arms: 0.3mm, >= 20% infill



The left and right arms are designed very tight, and some sanding is needed. Carefully sand and insert them into the panel until it fit, without struggling the front panel. It is essential that they not bend when tightening the belt, maintaining the belt-motor-pulley geometry.

Bolt and plate

The bolt needs some effort to fit into the plate the first time. Mine, at 0.2mm, fits nicely after the first time, neither too tight nor loose.
