6 coins in a box Puzzle

This is a puzzle where you have to put six ‘coins’ into a box so that they do not protrude above the edge. It is based of an original wooden puzzle featured in the YouTube video below.

Standard 0.2 layer height SPEED settings for 0.4 Nozzle
- Printed in PLA,  (here I used 2 chameleon colours).
- 10% infill. 

• There is an overhang at the top of the box on the inside, but it is filleted. I printed  without supports and this went fine.

It is about a 4 hour print (on the MK4S + MMU3)
Have fun solving.
 

[[spoiler alert, the video also shows you the solution in the end!]]
