Here are two samples from a program I wrote to create an image wrapped around a cylinder (i.e. a cylindrical projection.) This is fun for art purposes, and I have used it to make fun cookie cutters, molding fondant, making ink stamps, etc.

If you want to make your own, you can download the Python program at:

This program will create an STL file for an image of your choosing.

Have fun!
