The following steps will take a papercraft creeper and give your nerves a little more of a test when you hear the "hissing" sound and you turn around to see this little guy walking across your desk.
Step 1: Gather Tools and Items
* Paper clips
* Craft stick
* small Amount of Clay
** Papercraft Model
** Gear Box
Tools you may need:
* Screw driver
* flush Cutters
Step 2: Get a Windup Gear Box
Due to the Easter holiday, I've salvaged a gearbox from a walking chicken. After the you eat the candy eggs there is not much fun left in an empty chicken.
Step 3: Print Your PaperCraft
Step 4: Building the Body
Then glue the body together around the gearbox, adding some glue to hold the body in place will help.
Step 5: Making the Legs
Before sealing up the legs, add a tab of paper that will act as a hinge.
Step 6: Glue the Legs to the Body
Be Sure you leave a little space between the front two legs as well as the back, this will be where the crank rod will go.
Once the legs are on, you may assemble the rest of the body.
Step 7: Build the Leg Rods
unbend the paper clips to form straight pieces of metal. Using a pair of pliers, pinch the end and wrap the paper clip around to form loops.
You will need one small piece to act as the pivot and two longer pieces (long enough to reach from the top of the turn wheel and to the top of the legs. Bend these pieces into a "L" shape with the loop facing in. (see Picture)
The excess on the bottom of the "L" need only be as long as the leg is wide.
Step 8: Assembling the Crank
Do the same on the other leg, this time a little further away then the first hole. Place in the other "L" rod, loop facing in.
Place the smaller pivot pin inside the two "L" loops and glue it into the hole of the turn wheel.
Repeat these steps for the back legs.
Step 9: Finshed
You can use a windup gearbox in any project that uses a turn crank or a motor. Have fun and go out and add movement to all your favorite 3D models and papercrafts.
