My H2C complained that it needed some maintenance the other day, which is always fun. Lubing the leadscrews on these machines can be a bit of a hassle, since the rear leadscrew is a bit difficult to access. I got it done and it's really not a big deal, but it got me thinking about a nozzle for greasing the leadscrews. Bambu recommends a few types of grease for their printers, and one is Lucas Oil 10533 White Lithium Grease, which I'm gonna test on my X1C. I tend to prerfer the white lithium grease because it doesn't have PTFE like the SuperLube I had been using. It is also a bit cheaper, and since it's recommended I don't really see a downside.
There are plenty of cool designs out there for this type of thing, but I wanted one that I could cap off, and I was also looking for a design with a longer nozzle, to reach the back leadscrew. After looking over the options, I couldn't find one that did those two things, so I made one. The design is pretty simple, and seems to work OK. No matter how you cut it, lubing the leadscrews is a messy job though, but I will take all the help I can get. This does make it a bit simpler, and the cap certainly keeps everything more tidy. After printing the prototype, I decided to add a longer nozzle option as well, which may help with accessing leadscrews which are even deeper inside some printers. There is also a storage plug which can be used to seal up the nozzle, if the stock cap is used on the tube of grease. So far I think the design is checking all (two) of the boxes I needed, plus maybe one more in that the storage cap lets me keep using the tube for other projects, while keeping the mess of storing the nozzle to a minimum.
The design will be released soon on MakerWorld, and I will post the link here.
By the way, I haven't stopped working on the other projects, I'm just waiting on parts to wrap a couple of them up.
