The goal of the puzzle is to get the spade out but also find all 3 hidden drawers where you can hide a reward for each step
Note: This probably needs a very accurate tolerances. If it's not working for your printer, please feel free to edit them in the .step file
This was printed on a Prusa Mini+ and tolerance was set accordingly. Depending on your printer you might have to sand a bit or feel free to remix the OBJ files
Print instructions:
0.20 mm layer height
Some parts need minimal support and I found Prusa slicer's “automatic painting” feature does the job
Each part x 1 but Pins x 9
(Optional) Stand
Color the A and small Spade if you don't have multi-color
Assembly instructions with a GIF:
Place Lower Cover down
Put the Latch on the sliding hole
Position the Lower Drawer inside it
Prepare the upper drawer and the smaller hidden drawer
Place it on the top lower drawer so it fits flush
Close with Upper Cover
Use the 9 pins to lock them in place
Put the Ace in it's socket at the top
The pins fit tight for me but can be removed(one by one) with force so maybe consider supergluing to avoid brute-force attempts :D
Solution with a GIF:
Push the latch(central black) up to unlock open the lower drawer
Close the lower drawer
Push the latch up to unlock the upper drawer
With the upper drawer open, push the Ace down out of its socket
Ace will lock in the last hidden drawer and unlock it
