A simple stand for the sierpinsky pyramid.

The model was quickly made with Blender. (www.blender.org)

Included is the initial version and one with less material usage (Infill modified) as 3mf.
Feel free to change the Infill to whatever you like.
Maybe even infill to 0% and downscaling of the modifier cube.

The fit to the pyramid (dimension 109mmx109mm) on the stand is only one layer high (on 0.2mm layer heigth).
To get a more reliable fit, you can scale the Model in Z by e.g. 150%.

I only printed the less material version.

Happy Printing.
