Burr Bot by Andrew Crowell

Here's a description of the puzzle taken from the designer's website, arcpuzzles.com:

Burr Bot is a mischievous little robot. He has eaten something he shouldn't have. Can you open him up and retrieve what he ate?

As with all robots, he is quite logical and he does not like excessive force, to be shaken, or hit. Be careful he also has magnets and small parts.

Burr Bot is combination of a burr style puzzle (with interlocking pieces that can be moved around) and a sequential discovery puzzle (where tools can be discovered to help you solve the puzzle). He has been printed in Marble, Purple, Yellow, Gray, and Light Blue PLA. He does also include a number of magnets. Good Luck!
