My appartment has a hallway that isn’t particularly well lit, so it was obvious that I wanted to set up a lamp in the hallway. As an added challenge I didn’t want to put any permanent marks into the wall, as my landlord requires them to be fixed to original state again when I leave the appartment. Luckily, I have a set of heating pipes that I can use to mount the lamp, so I designed a custom fitting around the pipes, and built a connector, to which a spiral lamp is attached.

In the design of the diffusor I was inspired by some spiral plant pots that were surprisingly easy to 3d print. I learned that these could be designed using the surface modeling tools in Fusion 360. I combined the design with a bulb holder that I had lying around, and connected it using a standard electrical connector.

After designing the diffusor in fusion 360, I found it a little long for the hallway, and so I made the diffusor a little less tall.

The 3d printed connector pieces are made from a material called PETG, which is stable in temperature until about 80 degrees C. If the pipes become hotter than that, the lamp will likely fall. If that is the case, I’ll just reprint the green parts using ABS plastic that is stable even above 100 degrees C. In any case, I don’t expect the pipes to become any hotter than 60 C, as higher temperatures in a heating system will be very energy inefficient.

Compared to my other spaceframe lamps, this lamp only contains about 10-15 components, making it relatively easy to print assemble and install.
