Glass is great, and glass jars are great too! But, how do you take a bunch of empty jars and make them into a coherent elment of home decor? 3D Printed jar lids!
Inspiration for this came from seeing a bunch of classic buttons for sale, and realising just how iconic that design is. I'd been contemplating making jar lids, and that gave a great theme on which to base a design. So, here we are! And, while I was at it, I printed a bunch of actual buttons, too, and the files for those are attached.
Now, there is one important consideration here: this lid will fit a 62mm lugged jar. Not a screw-threaded jar. Not a different sized jar! Admittedly, I didn't know what a lugged jar was until I designed this, and started looking up jar specifications. Lugs are the little tabs inside the lid that slide down what look like partial threads on the jar. The ones in the photos are a good example. It seems that 62mm lugged jars are the kind I encounter most. If you want to take the design and adapt it for other sizes, that would be an awesome thing to do! I really should have approached this parametrically, so that it could be arbitrarily sized... *thinking face emoji*
Oh, and there are two lids included: one with holes going right through, and one with a solid top, just because.
So, there's nothing especially tricky about the print itself, just a little bridging, but there are a few things to think about.
Firstly, this is a printed object that needs to interact with an existing physical thing. So, dimensional accuracy is important. I printed one a lid using a shoddily-calibrated (by me) home-brew machine and it didn't quite fit, so it's certainly possible to mess things up!
Secondly, infill. The lugs will probably get infilled, and you want those to be reasonably strong, since they're just little bits of plastic holding the jar closed. So, maybe go with a higher infill percentage. It's not a big print, so the difference to time and material is likely not that significant, but the strength difference will be!
