I made this to replace the bed bushings on my i3 bed.
See for my previous setup and bushing holders these are designed to work with. https://www.thingiverse.com/thing:2538105
- Better for printing with petg. My pla bed bushings were slowly deforming over time due to the combination of bed heat and a warm enclosure. I've found that petg also works fairly well as bushing material and is more temperature resistant than pla. BUT, petg is a pain to print nice when there are frequent retractions. This is designed to print with just enough perimeters to connect inside and outside walls and no infill so you will have fewer retractions than many bushing models.
- Has a spiral center for even wear.
- Cable tie notch to help keep it in place in my holder.
No top or bottom layers, 2 perimeters, no infill
