Use to put a thin film of oil on your printer shafts.
For 8mm or thinner shafts.

Update March 15 2013:
My applicator leaked oil so I figured it must not have been water tight so I reprinted it with 100% fill. It then was a tight fit in the lid so I took 0.1 mm out from the inside of the lid and it is a good fit now. I have updated the STL file for the lid and instructions accordingly.

Instructions:

Print both pieces.
Glue a strip af 4mm thick low density rubber foam into the top of the applicator.
Squirt oil liberally onto foam.
Run oil soaked foam along shafts while turning the shaft as well if applicable.
Replace cap on applicator and stand upright.

Print Settings:

Printed with KISSlicer with 0.12mm layers
Applicator 100% fill (So it will be water tight)
Cover/Stand 100% fill to give strength to the legs.
