Z Rod Grease Can Focuser

Update 5/25/2021: I've included four new versions with beveled holes for the grease straw. Thanks to zolan for the idea. The idea behind rough or smooth bevels is to give better grip. I haven't printed these yet to test as my printers are busy with other projects, but I'll try when I get time. Thank you, everyone, for the kind words so far. If you would like to give me a tip, I'll put them in my "Burger Fund." Being an American in the Philippines, sometimes you need a taste of home.

Update 5/24/2021: I've included two versions with larger holes for the grease straw. Thanks, JimSheldon, for the idea.

I try to maintain my printers, and I hate getting grease everywhere when I spray my z rods down with white lithium grease. Using a piece of paper or a rag kinda worked, but I have a 3D printer, so I should print a solution!

This little piece slides onto the straw included with your spray can and then can go around the z rod. My straw is 2.4mm. Don't go crazy with the spray as it can still fly around, and I recommend having a rag or piece of paper behind still to keep things clean. At least any grease caught by this thingy can be rubbed onto your z rods.

I haven't printed the "(more coverage)" version yet, but in theory it should work. You can try to remix this and make the inside smaller I guess, but I didn't want to have problems getting this over my z rod even when in use.
