Created this Architectural lamp holder piece, as my son's original one broke a long time ago, and I remembered that the 3D printing would be a great idea to have it replaced.

The design based on the original piece has been done in Thinkercad- took me around 15 min to get it right. Measurements took at least the same amount of time.

I used a 70% infill with support on critical places.

Set the Wall to 6 to be as strong as possible, and it works like a charm :)

One of the images holds all the pieces as well as the original one next to it.
