About this 3D model

There are 2 puzzles to solve: Challenge #1 (hard) - arrange the tiles such that all 9 blades (radiating out from center to outer rim) add to 20, including the number on the frame. Challenge # 2 (moderate) - disregard the numbers on the frame and arrange the inner tiles such that all blades add to 15. The model include a handy cover, which keeps all pieces inside when traveling. Check also my other brain teasers designs. Please leave comment and rate. Thank you so much. Have fun! Print instructions 3mf files and hcodes includes color changes. Or slice it yourself without them.
