48-hedron conundrum

I remembered this simple toy/trivial conundrum from my childhood, when it was quite well known but I realized I didn't see it around for a while. I got it first time from a fair and I still remember my 6-years old being so proud for finally figuring it out. A few quick clicks in F360 and slightly over two hours of print time to hold it again. Hopefully, someone else will like that too…

Printing:

No supports needed; can be freely scaled obviously, this uploaded 3mf contains sizing of a bit over 5cm/2" diagonally. I printed with galaxy black PLA prusament but I bet it would look mesmerizing printed hollow with Orange transparent PVB prusament, I just didn't have any on my hand. I imagine it looking like a piece of amber…

First, let's dismantle the puzzle:

Now it's all about sorting three kinds of parts. First, make U-like shape from 3 two-cut parts:

Add 2 three-cuts parts alongside:

And slide in the last, no-cut part like this:

Try that five times and I bet you could do that blindfolded since then. Also, it's noteworthy that pressing against the cross-sections makes the puzzle more rigid (blue arrows directions), while pressing it diagonally or twisting it will make it lose to the point of disassembly (red arrows), because of tight tolerances of it's parts, resulting in surface friction. Obviously, fine tuned printer will help immensely here. Have fun!
