Floor lamp chassis for ambient lighting. Includes hidden drawer for wires and LED dimmer. I like using these LEDs: https://www.amazon.com/gp/product/B076RQR47S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1.

Print files include a base, top and repeatable middle segment. With 1 top and 1 base having
4 middle segments makes a decently sized (56.5" height) and stable floor lamp. For extra stability use plastic glue to glue each segment together to make the structure permanent.

To give a tint to the light and/or diffuse it a bit, I hot glue a thin strips of translucent colored paper along each flat edge.

The base needs to be printed by itself. The other pieces can be combined.
Print the segments vertically with the female end facing down and the male end facing up. Print the top piece vertically with the female end facing up.

If using Cura you might need to scale some pieces by a factor of 10. In case it helps, here are the dimensions to shoot for:

• Base
  • x: 189.1392mm
  • y: 189.1392mm
  • z: 246.3505mm
• Drawer
  • x: 145.5753mm
  • y: 79.6251mm
  • z: 40.3675mm
• Segment(s)
  • x: 44.851mm
  • y: 38.8167mm
  • z: 249.9995mm
• Top
  • x: 44.8512mm
  • y: 44.8742mm
  • z: 249.518mm
