Yet another LM8UU bearing greaser
Description
So my bearings started to get noisy, and simply dripping some PTFE oil onto the rails somehow didn't cut it. Looking at the bearing greasers already available here, each one had some specifics in the comments, often from the designer, why this wasn't exactly working as intended - or why it wouldn't work for me (like being designed for a specific tube of grease which wasn't easily available here). Therefore, first I obtained a tube of grease that was easy to get at my location - "CRC Super Longterm Grease + MoS2", 100 ml. Measuring the cap thread it looked like a 14.5 x 1.45 mm thread - however, after a test, I found that a M15 x 1.5 mm thread fit much better (i.e. I could get it on easily, while the 14.5 mm thread got stuck...). An inspection of the available grease injectors brought up an immense variety - short, long, angled - all with the aim in mind to reach the bearings of a printer with minimal disassembly. Since they all also had some comment stating that they didn't work always as intended, I'll try something new: short, slightly angled and offset. With a matching cap of course. WIP - right now, my <s>first</s> second attempt is printing. I'll update once this is done with some pictures, and hopefully some time around Christmas how well it worked in real life. Material: Prusament ASA Settings: 0.2 mm, 3 walls, 6 top/bottom layers, solid infill Supports: on baseplate only, you may want to add some support blockers Designed in Fusion360 - I'll add the project file once I'm reasonably satisfied with the design. Edit 09.12.19: realized that at the original angle, the grease tube might interfere in the case of bearings close to a surface (e.g. those under the build plate of the i3 Mk3); added a modified version with an inward angled tip.
