Description

20 Sided lampshade:
The hole in the base side is 40mm, each side of the triangles is 160mm long.

Materials and methods

This mode was created with a combination of OnShape and Fusion360. The model in the photos uses:

19x Icosa sides
1x Icosa base
12x joint

There are a couple of sizes for the joint. One with 3.1mm holes, one with 3.2mm holes, and one with 3.3mm holes. If I am printing the joints with FDM, I use the 3.3mm version. The model in the picture uses the 3.1mm hole joints that were printed on a polyjet printer.

All the side panels in the picture were printed on SLS printers (EOS P396) but it should be possible to print them on FDM as well.

I've assembled the final piece in a few different ways. Sometimes as a desk lamp, sometimes as a hanging lamp. Here a few different products you can use to set it up:

This is for hanging:
