Elegoo Mars tension bushing for table calibration

thingiverse

Update! Now there's an alternative version available that's already closed. Unlike the original metal one, which requires a slit, the PETG-made version works seamlessly without it. The standard bushing is made of some type of metal, possibly even cast. It's incredibly rigid, causing the grub screws to be nearly destroyed until the bushing grabs onto the ball. A significant amount of force is needed to tighten the screws, making calibration utterly impractical. Print this bushing with PETG and ensure it has enough perimeters so that it becomes solid. I'm confident this will not last forever, but for my use, it works surprisingly well, even though I made some for my stock. I have no idea whether this could or would work directly with resin parts straight from the Elegoo. It's likely too brittle...
