Insulated Can Cozy with Lid (Parametric)

Print with TPU. I designed it with integrated support to optimize it for single filament printers. Simply print it oriented with the lid down and support turned off,  then the integrated support will easily tear off. There is also a file available for people who have multi-material capabilities. I used 15% infill and 2 perimeters with a fuzzy skin on the outside for aesthetic reasons. The inside of the Cozy has vertical ridges to keep the can from becoming stuck while securely holding the can. Many 3D printed cozies rely on perfect tolerances to get a snug but removable fit and many 3D prints as well as many cans do not fit those tolerances.

The file was made in Fusion, and I made variables for each of the important dimensions. To customize it to fit your can, open the .f3d file in Fusion, select the dropdown arrow labelled “Modify”, then select “Change Parameters” which you should find near the bottom of the options. This will open a window with all the variables and their values. DT is the diameter of the top of the can, DC is the diameter of the whole can at its widest, and HC is how tall you want the body of the Cozy; I set it at the height of the widest part of the can.

If you do not have Fusion, but you have a specific size you need, comment the dimensions and I'll upload it.
