LM8SUU grease cap

Inspired by walter's linear bearing grease cap but for the LM8 short version linear bearing.

Needed this for a long overdue printer cleaning and overhaul.

(Time passes ...)

Finished the overhaul! First thing printed was this red cover for the grease cap. It is sized tight for an interference fit using TPU. More rigid filaments may need to scale it up by a few percent.
