Grease / lube injector with cap for LM8UU / LM8 / LBBR (8mm) and LM10UU / LM10 (10mm) linear bearings

After producing quite a mess while trying to grease my bearings, I quickly designed this injector for LM8xx and LM10xx bearings which fits on the original SKF grease tubes.
Just slide it in carfully, press and rotate the bearing - done (see attached video on https://www.youtube.com/watch?v=eEiKf8TaOOQ)
I added a cap so you can leave it on your tube
I also uploaded the step file in case you need different threads than M15x1,5
