Z-axis bearing protection

Boost MeYour contribution is my fuel for my projects, thanks

I designed these covers because dirt always accumulates in my printer compartment, they keep the bearing clean.

 

These covers were created so that they can be removed or lifted to lubricate the bearing or grease the worm gear.

 

Review of 04-11-2025 dd-mm-yyyy

I have added a print profile for those who want to reach all the way to the end of the print bed. I removed 1.6 mm from the original and did the tests.

They do not create any obstacles to the printer.

 

PROBLEM TO BE SOLVED:
The printer started to squeak, the grease and the bearing didn't get along with the dirt I created.

 

PROJECT: Fusion 360
I did various tests to make everything so precise, i kept the inclination of the printer so as to have a better aesthetic.

 

PRINT SETTINGS:

Print it with any material, I used Bambu material.

-Ugello 0.4mm

-Layer height 0.12mm
-No Supports

-100% filling

-3 Walls

 

ASSEMBLY:

The joints are held by the offsets given by the screws and the assembled pieces.

 

I cleaned everything, removing excess grease, put the grease directly on the worm screw

 

 

 

Note: with a little patience you will be able to mount the covers also on the screw at the back.

 

DISASSEMBLY:

Very simple to dismantle the protection, to be able to carry out maintenance or an aesthetic change if you like.

To carry out maintenance, I personally raise the protection and lubricate.
