This is version 2 of my fidget cube. I included as many features as possible without increasing its size. There are 10 different fidgets. 

Instructions:

Step 1: Add a small lever with the point facing the center of the cube on the small pin.

Step 2: Slide the wheel onto the larger peg.

Step 3: Take the two small buttons (arrows up slanted sides facing the peg) and fit the pins into the small grooves.

Step 4: Take the divider and slide it into place over the wheel and buttons. (Ensure the top pins on the buttons fit into grooves on the divider)

Step 5: Add the switch to peg on the divider.

Step 6: Take the larger button (the one with the spring) and fit the pin into the groove on the divider after sliding the spring into the hole.

Step 7: Take the slider (arrow side up) and fit it into the large groove on the side of the cube.

Step 8: Take the top divider and fit it on top of everything.

Step 9: Take the lid and snap it into place. (You can add a little glue if you like)

Step 10: Fit the three gears onto the three pegs on the side the cube. (Large one in the center, thicker small one on the left of the large one, and thin small one on the right of the large one)

Step 11: Take the knob and push it the in the bottom of the cube ( may require a little force)

Add a keychain if you like.

I hope you enjoy it.
