Hexagons Musical Pyramid

I created this one from scratch, inspired by Satisfying Hexagons, by the lazy engineer and its derivatives, including Hexagon Magnet Toy, by aaronjasso.

I didn't like the magnet approach. A holding knob was the first thing I changed, and then it really bothered me that because all the hexagons are separated, this easily falls apart.

So I recreated this by slicing a hexagonal pyramid. Once I got slanted hexagons, I wanted to be able to pull them up without them falling apart. It took a few iterations to get the exact ration between thickness and overlaps, but this worked out nicely eventually (and it can still fall apart if you insist).

As a surprising bonus, this actually plays a nice musical effect when you move it up/down (at least when printed with Silk PLA). I added a bigger knob version, which is recommended, as the small version tends to be fragile.

The HEX2 version seems to be easily separated, so I added HEX4 which has a tighter slope for better grip.

No support needed, use 20% infill or more on the knob. I printed with 0.2 / adaptive height (cura).
