This 3D printable puzzle Dalek has 3 stages to be completed before the head gets unlocked and you can pull it off to find the secret item inside! There are three stages to be completed in any order: A button to be pushed, a knob to be turned, and an RFID tag to be read. One of the LED's on the head of the Dalek will light up after each task is completed. Once all three tasks are completed and therefore all 3 LED's are on, a servo will unlock the head from the body and you can take the head off which is attached to a "cage" that contains the item.
