sliding lock puzzle

Challenge your brain with this mechanical padlock-style puzzle, The puzzle features a U-shaped shackle and a set of sliding cubes and rectangles that must be moved in the correct order to “unlock” the mechanism. the design has a “key” of sorts to help move the blocks around to make solving easier

a fun toy that doesn't take to long to print and is quite fun!

assembly -

this is the starting position.

then place the top cover on, you may glue this in place but i've found the friction holds it in well enough for most cases

when solved it should look like this
