Summary

Made this for can collecting. We all know that the guys at Monster Energy HQ make a whole lot of flavours. If you want to collect the cans you have drunk and seal them off, print this. It's a friction fit, so check tolerances. You could still sand a bit to make it fit the can's opening. Also note, due to the friction fitting, it might be difficult to take it out of the can.

Print the object with the smaller diameter facing up.
Takes around 10 minutes to print.
