Kossel 2020 Arm Tensioners

thingiverse

I crafted this component specifically because there's a slight amount of wobble on the arms of kossels that causes noticeable jitter in prints. This issue is typically more apparent in colors that reflect a lot of light and reveal layer lines clearly. These parts also assist with prints requiring high tolerances. Simply print two of these components, then secure them together using two rubber bands to bring the arms closer and hold them firmly in place. Alternative mods often employ a combination of rubber bands and zipties, but this approach is more refined and efficient.
