**Update:** I've made a solid version of this thing that will have it's own remix, after a few more are printed and quality pictures taken. I named it "Just a Jar" & "Just a Lid". Until then, the files are attached here.

*Updated 2 Dec-13-2025* Holes are now smaller on the sides, bottom, and lid. I remade the entire project from scratch with diamonds of 1.5mm x 3mm point to point. Edge to edge distance is under 1.4mm. This should give it a much tighter mesh. I've also removed the diamonds from the neck of the bottle to improve printing for a few people whose printers did not like an overhang with holes in it. Additionally, I've build and uploaded a funnel for easy bottle filling. Enjoy!

### **Education For New Makers:**

In 3D printing, it is important to keep your filament dry. Practically every type of plastic will take on moisture from humid air. In technical terms, polymers are hygroscopic. PLA and ABS/ASA less so than PETG/Nylon/PolyCarbonate and flexibles, but it will eventually be a problem with enough time in the open air.

The solution is to store open spools of filament in containers which are as close to air tight as possible, and to include silica gel desiccant…
