IQ Puzzle Cube

I stopped uploading and updating my models here at Printables!

My actual models can be found on my MakerWorld profile – with print profiles.
Take care to use the newest models …

Harder than I thought. Put all 25 pieces in the cube holder.

Just print the puzzle piece 25 times  and the cube holder once.

No support needed. I used 2 walls and 15% infill.

I uploaded a pdf with one possible solution as proof that it's solvable.
