Stronger Printable Keys for Treasure Chest

3D-printable keys for the famous Treasure chest.
The well known version has a key hole size of 4.6 mm -- so that a lasercout key of 3x3 mm would fit. This is quite fragile. I rounded the key to 4.4mm diameter, that makes it much stronger.

Note, that I have my own version of the chest, where the key hole is larger. The keys_jw.stl fit there, with a diameter of 5.6 mm.
