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.


After some struggle with Cura I manage to understand how to get a raft even if the maximum size of the part is as large as the maximum dimension of my printer (but the base is smaller so there should be enough room to get a raft, I cheat him first and say no raft, when he sliced the part once I tell him add a raft and in this order he makes it.)
So I printed with a raft otherwise the dimension sticking to the plate is really really too small.
But I wanted to save some time and set up the parameters with thin walls (2 lines) and low infill (10%), as a result the walls are not straight. It alreadu took 5 or 6 hours
I'll do it once more later on.

How I Designed This

I used Fusion 360 but the basic settings were NOT with Z facing upwards but Y so you'll need to turn the part before printing. I'm still learning !
