Simple electrical cabinet lock

In the building where I live there's a comm cabinet in every flight of stairs, and as it happens nobody has the keys. Not that they need to be secure, but the result is that everytime someone needs to do any work inside those cabinets they end up breaking the locks or even the door itself.

As there's no need for any kind of security I designed this simple rotating lock as a replacement. It's intended to be operated with a coin or a big flat screwdriver, so hopefully the'll last a bit.

The cylinder is designed as a two-part single piece that can be printed in one go without supports. To install just push the cylinder in the door from the front and lock it in place from behind with the pressure-fit ring. Attach the cam in the back and secure it with some adhesive.

I printed them with PC+CF but I guess PLA or PETG should be enough.
