Description
We use this with students in our school.
The goal is to find the right arrangement to fit all 6 T blocks into the box. Really makes you think! It's possible (as shown in this video)! For the most fun, try to solve it without watching the video to find out how!
No supports needed.
PLA is fine.
I used a 0.4 mm nozzle.
I printed at 0.28 mm layer height, but 0.2 mm could work too.
Print 6 of the T blocks - "T-Block-x6.stl"
Print 1 of the lid - "Shell Lid.stl"
Print 1 of the body - "Shell Body.stl"
Using CA glue, attach the lid to the body.
