Double pyramid puzzle

Double pyramid puzzle This puzzle consists of 2 identical pieces, so it is rather easy to solve. However, if you look at a single piece, it is difficult to imagine which geometric body results from the puzzle. Print The model can be printed without support. However, there may be problems with bed adhesion due to the small contact surface. I therefore recommend using PETG and/or a brim. The print worked for me without a brim. Downscaling to 80 pct. is no problem.
