Needed a basic can holder that could be screwed into a surface, and since I couldn't find any model that matched that requirement, I came up with a quick design myself. Turned out it worked quite well, so wanted to share it.
Didn't make it solid all the way around, so it was easier to drill the screws in, and to get a better grip of the can inside. Used two 3,4 mm screws to mount it in my build.
