Some days ago I was offered the short https://www.youtube.com/shorts/SvN4KrNSFyI
"Amazing geometric space skills, can you imagine it?" on Youtube. Though I found this an interesting puzzle, I couldn't find it for my 3D printer, because I missed the correct name. So I decided to create it myself with the help of the video.

The goal is, to fit the mini triangle together with the 7 other pieces in the bottom. If You don't find the solution, You can watch the video ;-)

Later I found the puzzle by chance on yeggi, so alone on thingiverse there are already 3 versions published: https://www.thingiverse.com/thing:6718494 https://www.thingiverse.com/thing:4978789 https://www.thingiverse.com/thing:6741172

I combined Geeetech brown PETG and Giantech marble light brown PETG, so that the pieces have a good contrast to the bottom part. Even if You want to print the mini triangle in a different colour, this is possible, because I separated it from the other pieces.

As with all these puzzles, tolerances may be critical. If the pieces should be too tight, depending on Your printer calibration and settings, You can either upscale the bottom a little bit, or try the CURA setting "horizontal expansion".

Have fun :-)

UPDATE on 11/23/2024: As with all these puzzles I don't like, when there is no real storage for the pieces. So I also added a cover for it :-) It's designed with 0.4mm tolerances, so if Your printer is well calibrated, it should just fit with only a little pressure.
