Mercator planisphere

I know it’s not useful, but I wanted to make one for fun. Way back in 1991, I took an astronomy class and that is what we did. We had to supply a Pringle’s can and they gave us two sheets of paper.

The first sheet was a Mercator sky map that we cut and glued on the Pringle’s can. The second sheet was taped together and rotated around the can. I have googled and found zero on making one, all the DIY planispheres are the usual flat circular ones.

I have used Stellarium and created a Mercator map and inverted the colors. I also have the Pringle’s can dimensions. Does anyone remember making these?
