Mass Portal Pharaoh XD20 Delta Tensioner

thingiverse

Earlier dual-port designs utilized two rubber O-rings per delta side to preload the ball joints, one situated next to each joint pair. These components inevitably perish and detach. The last unbroken O-ring of the six fitted ones proudly sits in the center of the image. This single TPU belt replaces both previous units, offering a viable alternative solution. Although it may not be the most ideal choice, it functions effectively. The belt's tension can be adjusted for your printer by scaling down or up along the Z axis. It was specifically designed for the XD20 model, but its compatibility with other Mass Portals is uncertain due to size constraints. However, through careful scaling adjustments, it could potentially fit a variety of delta printers beyond the Mass Portal range.
