Description
Optimized for easy and fast 3D printing, this Smiley Case features a print-in-place hinge and snap-lock mechanism, so no installation or assembly is required.
A keychain hole next to the hinge allows you to easily attach the box to your keychain.
When folding the box for the first time, you may need to use a bit more force due to the print-in-place design. Please close the box carefully on the first use.
The case is available in three pre-made sizes and can also be scaled to your desired size. (scaling between 75% and 200% is recommended).
Dimensions:

Update (21.05.2026): Reinforced hinges + snap-lock, and adjusted the print profiles for improved strength.
