Introduction: Lego Puzzle Box No. 1 'First' (And Other Boxes!)
Hello! After a long hiatus from Instructables, I am back! I have a bunch of puzzle boxes I have made, and I plan on posting instructions for all of them. I would love to know which one I should post next! Above are all the currently working and built boxes I have that I have not posted yet, except First.
Here is an overview of the boxes, including instructions that have been made.
Difficulty of the boxes: (1) to (10)
Storage in the boxes:  to 
First: 3 moves, , (2)
Yellow: about 3 moves, [3.5], (8.5)
Instructions and more for Yellow
Diamonds: about 3 moves,  (3.5)

Step 1: Videos
Here are videos about opening and closing the boxes.
Step 2: Better Pictures of First
This is my first puzzle box. I disassembled this one a while ago, so clear instructions cannot be made. This is the box I posted a while ago, but with 'censored' pictures. I feel that the box is simple enough to be made just by looking at these pictures, but if needed, I -could- rebuild it and make more detailed instructions.
