Description
A grease applicator ("bearing pacifier") for LM8UU linear bearings, modified to thread directly onto an Inox MX6 30 g grease tube. Slip the LM8UU over the nose, give the tube a squeeze, and the bearing is greased evenly and cleanly — no mess, no cotton buds, no wasted grease.
This is a remix of Honza David's Prusa Lubricant LM8UU Adaptor (Bearing Pacifier), re-threaded specifically for the Inox MX6 30 g tube, which has a different nozzle shape and thread to the original Prusa lubricant tube.
Greases LM8UU linear bearings cleanly and evenly
Threaded to fit the Inox MX6 30 g grease tube
Extended, re-profiled threaded section for a secure fit
Quick, simple print

💡 PLA is fine here — it's a light-duty workshop tool, not a structural or heat-exposed part.
Print in PLA.
Thread the applicator onto the Inox MX6 30 g grease tube.
Slide an LM8UU bearing onto the applicator nose.
Gently squeeze the tube to push grease through and coat the bearing.
