These are some coin tubes that work perfectly with Australian coins. Currently there are only ones that are 60mm tall but there are some taller ones to come soon. Check my uploads in about a month and I should have a coin tube container and a sorter that allows you to dump coins on a tray and push them into a corresponding slot.
NO INFILL (just use 3 shells)
White or any other transparent filament
Any transparent filaments are preferred, since you can see how many coins are in there. But they are not entirely necessary, you will just lose that functionality
If you use CURA, combing is recommended to prevent stringing, and any other filament nuggets.
