This automaton is a dog jumping and a dog bowl spinning
Step 1: Materials
Get all of your materials from a store like Michael's. You will need the following:
2 6"x6"x1/4" wood panels (walls)
2 11 1/4"x6"x1/4" wood panels (roof and base)
1 3 1/4"x1 1/2"x1/4" wood panel (handle)
2 1"x3/4"x1" wood blocks (blocks)
2 12 teeth 2 3/4" diameter gears
2 12" long, 1/2" diameter dowels
1 3-D printed dog
1 3-D printed dog bowl
1 4"x3"x1/4" wood panel (base for dog)
1 3 1/4"x3"x1/4" wood panel (base for bowl)
1 1"x3/4"x1/4" wood panel (stopper)
1 12" long, 3/8" diameter dowel
1 2 3/4" diameter circle cam
2 1/8" thick, 3 1/4" from top of drop cam to bottom (drop cams)
Drill with 1/2" and 3/8" bits
Hot Glue Gun with glue
Step 2: Drill Holes
Drill two 1/2" holes in the walls
Step 3: Glue Drop Cams
Take your two drop cams and glue them together with wood glue.
Step 4: Sliding in Position
Take one of your 1/2" dowels and slide the now one drop cam and one of your gears onto it. Then put the dowel into the two holes your drilled earlier.
Step 5: Glue Walls
Glue the walls in place on the base with wood glue and the blocks to help hold them in place.
Step 6: Drill Holes in Roof
Drill one hole that is 1/2" and another that is 3/8" on the roof. Before you drill the holes make sure that when you stick the dowels through them the dowel will slide right on top of the main dowel going between the two walls.
Step 7: Sand Holes
Sand the holes you just drilled so that the dowels will easily slide through.
Step 8: Drill Holes in Dog and Dog Bowl Bases
Drill a 1/2" hole in the bowl base and a 3/8" hole in the dog base.
Step 9: Glue the Bases
Glue the newly drilled bases to the bottom of the dog and dog bowl with hot glue. Make sure little glue gets in the space where you drilled.
Step 10: Insert Dowel in Bases
Put a little hot glue into the hole drilled in the bases and then insert the dowel into the hole. Wait till the glue hardens then put the dowels through the holes in the roof.
Step 11: Attach Gear and Circle Cam
Slide the 1/2" dowel into the hole of the gear and hot glue the center of the circular cam so that it will attach to the 3/8" dowel.
Step 12: Put Stoppers on Dowel
To prevent the dowel from sliding out attach duct tape on the inner edge of the dowel and the stopper on the outer part. When doing this make sure that the part opposite to the part where the stoppers are is not sticking out whatsoever.
Step 13: Drill Hole in Handle
Drill a 1/2" hole on the edge of the handle.
Step 14: Attach Handle to Dowel
Hot glue the handle to the end of the 1/2" dowel.
Step 15: Automaton
Your automaton is now finished and should look like the image above
