A couple Yeti Colster Can Coolers got me to make tops to fit various can sizes. Hum… why not make a bottom too? So this is a bottom, that has Yeti like threads. I printed this with shell of 2 and 25% infill for double walled insulation. Print bottom, bottom down and tops thread down (should be default position). Filaments PETG & PLA+ did not need support YMMV.
The top caps here are the same files as the ones shared for my other Yeti can tops thingy post.
FWIW… I’ve been told the threads work on other stainless cooltainers too.
Added another bottom file (v4). To reduce excess gap between the top cap and bottom the inside depth increased 2mm. Also, the excess extra air space in the bottom got reduced 2mm for a total of 4mm less height.
So, while these were fun ... I didn't like the fat cover and the top lip is awkward, so I made a design that I like better ... jump to my slim can covers here: https://www.thingiverse.com/thing:3370281
