GigaBurr 3D Puzzle: The Next Level

If you liked the regular GigaBurr 3D Puzzle that has inner 3x3x3 grid and requires 8 moves but it was too easy for you, here is 4x4x4 variant that requires 18 moves.

My colleague likes puzzles and playing with various algorithms. This is combination of both where this GigaBurr puzzle was created by “simulated annealing” algorithm in Python. Printed from PETG with 0.4 mm nozzle. Use 0.2 mm (or 0.1 mm) layer height to avoid rounding impact to the segment spacing. Supports “from bed only” are sufficient.

But again - the puzzle solved in less than 30 minutes after print. Let me know your time in comments. Have fun!
