Z Wobble fix for Geetech Acrylic i3 Pro B (8mm threaded rod)

thingiverse

This is my solution to the Z wobble common to Geetech Acrylic i3 Pro B printers with 8mm threaded rods. It has completely eliminated the issue that was plaguing me, leaving me amazed at how freely the threaded rods now turn. To implement this solution, you will need to source four bearings with a 16mm outer diameter and an 8mm inner diameter. I strongly recommend drilling out the acrylic top plate using an 8.5mm drill bit for optimal results. Additionally, if your printer is equipped with Z axis mounts, you will need to turn the brass axis nuts upside down, ensuring that the longer flange faces upwards when inserted into the printer mount. The bottom bearing mounts have undergone a slight design change in the STL files compared to the initial version shown. The pictures demonstrate parts printed in PLA, but I am currently reprinting and replacing them with PETG for enhanced durability.
