I keep running into awesome things you can do with InstaMorph. I had a bunch of beer bottle caps that I needed for a project, but they come kind of flattened out, and the only way to shape them into the standard bottle cap shape is to use a capper tool to seal them onto a bottle. Then you have to carefully pry it off the bottle, probably denting the caps along the way.
Instead of going through that hassle, I just created a cylinder a little thinner than a beer cap out of Instamorph. I use that in place of a bottle, and use the capper tool to clamp the cap onto the cylinder. Since it’s a little smaller with no grooves, the cap goes on perfectly, then pops right back off with the perfect shape. The cylinder was a bit wobbly so I attached it to a flat base to stabilize everything. Perfect bottle caps every time!
