Press the present. It clicks. 🎁
I hid a keyboard switch inside a Christmas present, so the whole lid, bow and all, is the key.

It is fully parametric. Press Customize, pick a size (26 to 80 mm) and a color for each part, and it generates your own version. It snaps together with no glue and prints with no supports. You need one standard keyboard switch. The bow has an eye for a keyring.
This is the second design. The first had the switch sticking out of the bottom of the box with a keycap underneath. I redesigned it so the lid itself is the key, which is why the ribbon is split in two: the top half rides on the lid, two bands stay on the box.
The photos show my red and white clicker. There is also a classic version with no switch: the lid comes off and there is room for a small surprise inside.
If you print one, post it as a make on the model page, or send me the photo here.
