Fractal "Fairy Crystal" small 7 sides

A variation of the Sierpinski Pyramid, reworked to have 7 sides.  

Recommend slicing with 0.3 mm layers to get best optical properties.  Use translucent PetG.  1 perimeter, 0 infill, 0 top layer, 0 bottom layer.  Add a height modifier near the top and set it for 100% rectilinear infill so the tip will be solid and not easily break off.

Postprocessing: Clean up the top with an razor knife or similar sharp blade.  Briefly expose the part to a heat gun to get rid of any tiny strings.  Don't over heat and warp your crystals!

There are 2 gcodes, one for single material, one for multi-material with filaments loaded in order: red, orange, yellow, purple, (unused so it doesn't matter).

These were printed with Prusa mk3s+ with MMU3.  

Cut out a quarter of the model, scale and rotate, to get 7 sides instead of 4.  Adjust size and order.  Add a mirror image vertically to make a base that raises the pyramid off the ground for artistic reasons.  Carefully choose where to slice off the base to show the “crusaders cross” on the bottom side.
