NOTE: You will need to remove these for tall models!! There is about a 25mm long linear bearing on the bottom of the bed at each Z-axis rod that goes down into the holes. They will crash with any model over 225mm. 

I got tired of debris (and sometimes screws) falling in the holes around the Z-Rods in the floor of the Centauri Carbon, but I couldn't find any covers for them. I took inspiration from the debris covers for the bed and the Z-axis screws and designed a two-piece cover for the Z-rod holes.

The tolerances are tight, so bed leveling and first layer are super important. I suggest putting them together and taking them apart a couple times to ease installation. If you still have problems, try increasing your elephant foot compensation.

I printed in PETG with a 0.4mm Nozzle and .08 layer height (though I'm sure .12 or .16 would work just a well)
No supports or brims needed. 
You will need three of them. 
Total material is about 2g and takes about 15 min to print.
