Tryamid Puzzle

UPDATE 02/22/22:
deleted files with "loose" in the name. If you want a loose fit, rotate the vertical version to have the largest surface on the print bed.
Added a tighter version to print the original vertical model to lay with the largest surface on the bed. If the original vertical version is printed horizonatally on the bed it will print too loose.
Added a new horizontal tighter version with holes.

UPDATE 02/12/22: Added file, pyramid1-3-NoExtra_Surface.stl. That is a tight version.
I noticed that a surface I used to slice the 3D solid showed up in the stl file, but it will not print since it has no depth. So, it should not matter using the other stl models with the extraneous surface.

This is an easy pyramid puzzle. It is very pointy so NOT RECOMMENDED FOR SMALL CHILDREN!
The three parts are identical and make a nice desktop doodad in three shades or colors.
I used Poly maker PLA and PETg at .20 and .25mm layers.
There are two versions, one tight and one looser for those who have trouble printing the first version.
Printing three at the same time is faster. If you do it three times with different colors, you can sort colors to have three puzzles with three colors, so there are per-arranged .stl files with three pieces.
