There was a triangular wall mounted bakelite outlet in my house which unfortunately broke in multiple spots and since it was possible to touch the live contact directly at one point it posed a hazard which I wanted to quickly eliminate.
Thus I designed this model after the real world measurements.

Important:

- this is not optimised for 3D printing and with its 29° angles most definitely requires supports in one way or another. Feel free to experiment and it would be great if you could share what works best for you

- printing outlets is a difficult topic. It must be taken into consideration that outlets can heat up when there's insufficient contact between the plug and the socket or if the socket happens to be corroded. As well as that, 3D printed outlets are NOT officially certified and may even be somewhat forbidden in some places. So use at your own risk!

- this model is by no means the universal design standard for triangular wall mounted outlets. this is a niche design made to fit a specific type of contact body which also happens to use a triangular ground contact fork that needs to be tensioned in with a separate piece from the top.

With all things said I still hope someone will find a use for this. Otherwise I just wanted to get this out there.
Have fun!
