Update date: February 22, 2022:
The model with the word "loose" in the file name has been deleted. If you want to print a more fitting finished product, you can rotate the original vertical model and place it so that the maximum plane is facing the printing platform.
A more compact version has been added, which is used to print the original vertical model so that its maximum plane can fully adhere to the print bed. If the original vertical model is printed on the print bed in a horizontal position, the finished product will often appear too loose.
In addition, a new compact horizontal model with holes has been added.

Update date: February 12, 2022: A new file, pyramid1-3-NoExtra_Surface.stl, has been added. This version features a compact design.
I noticed that some surface information used when slicing a 3D entity was accidentally written into the STL file. However, since the surface had no actual depth, it wouldn't have any impact on the printing process. Therefore, there's no need to worry about using other STL models with redundant surfaces.

This is a simple pyramid puzzle. Due to its sharp shape, it is strongly not recommended for young children to play with it!
The three components are completely identical, each adopting three different shades or colors. When combined, they are both beautiful and practical, and can be used as desktop decorations to embellish office desks or study desks.
I chose PLA and PETg materials from PolyMaker, and set the layer thickness to 0.20mm and 0.25mm respectively.
To facilitate those users who encountered difficulties in printing the first edition, we specifically provided two versions: one is more compact, and the other is slightly looser.
Printing three models at the same time is not only more efficient, but if you use different colors for printing three times, you can also sort them by color and easily assemble three sets of colorful puzzles with unique features. For this reason, we have thoughtfully prepared three sets of pre-organized STL files for users to call upon directly.
