3D model description


Replica of the PTT master key T10 used by the factors, the model is based only on scans and photos of my HNE3.

No caliper measurements or impressions, the same technique was used to duplicate the TSA mats.

I don't recommend however to produce it in order to try it on a letterbox cylinder (it's plastic, it breaks easily, and you will probably need to sand it a little, at least it will depend on your mastery of the printer)

In short, save it for your snares, it's easier.


T10 master key i did a while ago for the pleasure of increasing my 3D master keys collection.

Originally, this key is used by French postmans to open letterboxes.

I don't recommend using it on your letterbox due to plastic who tend to break easily and as it's also a question of printer settings, sanding etc., so keep it as a prop it's more simple.

May only the challenge guide you to print a working one :)

This reproduction is based only from pictures of my key (no caliper!), same process who got used for duplicating the TSA master keys.
