We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

About this print

A part designed to reduce Z-axis wobble on the Anet A8 desktop 3D printer. It seats a 608ZZ bearing to support the Z leadscrew and dampen unwanted lateral movement, which can cause visible banding in printed surfaces. The device is intended to improve print quality and is designed to work alongside other printer stabilisation upgrades. ABS is the recommended material as it provides a snug fit for the bearing, though PLA may be used with minor adjustment.

Original maker's notes

I made this device quickly.
In the following planned to make changes.
But the device is already half a year, works well, decided not to change anything.
Bearing 608ZZ.
We print leisurely with good resolution and filling
It works great in conjunction with this thing http://www.thingiverse.com/thing:1858459

I print in ABS
ABS has a shrinkage.
In other materials bearing landing can be free.
Heavy landing bearing is not needed ..
If it is very bad, use a drop of glue (PLA) , a drop plastic dissolved in acetone (ABS)
No need to use super glue or glue with strong fixation

I purchased and installed new screws.
Screws of high quality
I removed the anti wobble system and the upper bearing.
Print a test blocks before and after. (AVS label with anti wobble system and old of screws)
The printer prints with new screws bit cleaner, but small waves the axis Z visible. Even more strongly felt irregularities to the touch
Most likely I will go back to the previous configuration, but with the new screws

I added a photo of a similar device installed on my old 3D printer(PRUSA i2).
It is already working for 4 years.
This is the basis of my concept
