The whole idea behind this lamp is this is based on nr 7 or multiple of 7 which I like. There are 7 sides, 14 arms, each arm holding a profile polygon with 7 sides (heptagon).
All the arms are hollow and comunicate from top to bottom therefore you can add the LED inside and no wires will be visible. I have designed two interchangeable caps for top/bottom with different heights. Basically one can add batteries inside on either top or bottom instead of wires to exterior which is the route I chosen. I have only used 12V LED strips which I cut and soldered individually as they don't dissipate too much heat.
The top and bottom hepta pyramids have threads for easy removability. My thought was that you can unscrew the bottom hepta prism and replace with different designs of your own with different colors. They are printed without any infill so the LED will illuminate the 'removable' light fixtures.
The lamp is quite large once assembled but it can fit on similar print beds like Prusa MK2 or similar which I used.
