Is there an STL for the Prusa lubricant applicator
I'm going to be doing the MK3S to MK3S+ upgrade and wanted to take the opportunity to do some maintenance on the printer as well, I was looking at some topics on here and found the Prusa Lubricant Applicator in the Mini assembly guide, but can find it anywhere else, no STL in the parts kit for the Mini, no accessory on the shop etc., it seems its made specially for the Prusa Lubricant tubes, which would make lubricating the bearings a cake walk, but as previously stated its nowhere to be found, nor can I find a comparable adapter that would fit the Prusa Lubricant tube itself.

Thank you!

You're awesome, I couldn't find this at all! Thank you so much!

Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race. The bearing now has to work much harder to push the rolling elements through a mud bog of grease.
The increased friction and pressure from too much grease raises the temperature inside the bearing. Excess heat could decrease the effectiveness of the lubricant causing the oil to separate from the thickener. Not adding enough grease has the same life-shortening effect.

My big question now is how much should be applied? Should I forgo using this tool?

I would start with half a gram and then move the linear bearing back and forth on the guide shaft a few times. If the balls are not all coated with grease, re-grease a little.
Here is a comparison of how much is approx. 1 gram of grease:
(1 Eurocent)

Understanding that this is an old post, I thought I'd mention that while building the MK4 Kit I ran out of lube ( its a long story ) and I picked up one of these https://www.amazon.com/Super-Lube-21010-Grease/dp/B005R2NIIC/ref=sr_1_5
You can simply cut off the long tube under the cap down to the threads and the original Prusa applicator screws on perfectly. 12 grams of lubricant available to make a mess out of instead of the 4 grams Prusa provided in the kit.
