Printing tips:
Print always with support touching build plate! (There is a little overhang). I prefer to print this model with 100% infill.
Material:
This model works well with many of plastics. I have tried PLA, Colorfabb PLA/PHA and Colorfabb XT (copolyester). ABS should work well as well but it might be a little too flexible (a part of the opening force goes to flexing so the opening process requires more force). I think PLA is awesome material to choose for this print!
Steps:
Glue the coin and the magnet or either. (Edition 2,3 and 4)
Add a keychain or some string to the hole.
TIP: Glue the coin as well as possible. The product has to be very solid. It won't break unless it is not solid enough. (I have printed so many of these and only one broke up caused by bad gluing.
