3D printed padlock

This is a little 3D padlock I created.
Most parts are 3D printed, but you will also need some additional metal parts.
It is actually working very nice :).
Some parts are not that easy to print, like the little ball bearings.
Scale one ball a bit bigger, so that you have one in 5mm and one in 5.5mm, the bigger one goes to the shackle side.
The key is uncut, you can use a file or a keycutter to modify it for your pinning.
Additional parts which are needed:
- 5 keypins
- 5 drivers
- 1 long
