This koozie or cup is built for a typical 66mm can (where I live at least. You should measure!) Obviosley you can scale the koozie to make it fit whatever you want it to.

Could probably also be used as a cup, it has typical cup dimensions.

I have a very cheep printer (I want to upgrade), and printed it very fast, so I guess you can easily perform better (Please upload fotos if you do!)

I used 30% infill (You want those honeycomb airpockets to help isolate, in order to keep your drink cold)

I used a layer height of 0,2mm

I printed it in ABS, as I only had that filament color in ABS.

I used raft and support.
