Holder diameter is 66mm, same as my cans (I think this is some standard size) - you can check on picture
Made with following requirements in mind:
I thought that drawing it myself will be faster than checking other designs available, and now I can share it with you all - sharing is caring
I would recommend to print it in a way that layers go from base (when can will be sitting) to top (NOT from back to front) - having holding ring made from ring-like layers will make whole thing stronger
