51° pyramid for Schuman resonator

thingiverse

This is a pyramid designed for a friend of mine who did not know it was possible to make an "empty" pyramid with a 3D printer. He told me that the angle should be exactly 51,51° to get special properties. So did I. Inside he wants to install a Schuman resonator. It is supposed to send good vibes. The model Pyramid51 V2 can be assembled (glued) with the baseV3. They are both with a base of 180mm which is basically the maximum dimension I can print with my first printer. The diamond is a first try design to get them in one part with a bigger printer (maximum base is 200mm). But it's not yet printing. I will update it once fixed.
