Triangle Puzzle

Some days ago I was offered the short

"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:

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
