Lily Pad Spin is another ride in Froggy World, the amusement park for adventurous frogs.

This ride, designed by my wife, is for the "family" frog. Mom, pushes a stroller of tadpoles while Dad manages the older siblings. Frogs have a choice of riding the "spin" or sitting atop the bouncing spring.

Mechanical parts--motor holder, spring holders and lily pad rotating base were 3d printed, files here:

Step 1:

Start with the printed base and add a Jameco (#155821, jameco.com) gear motor. This press fits in the base.

Step 2:

Using 4 inch by 6 inch by 1/4 inch plywood, I glued together the sides of a box.

Step 3:

Add two pieces of 1/2 inch plywood (one for the bottom, one to elevate the motor).

Using wood screws, mount the motor.

Step 4:

Make a top using 6 inch by 6 inch by 1/4 inch plywood. Cut a large hole in the center. Fasten this with two small screws.

Paint the box.

Step 5:

Title the ride and add baked clay lily pads.

Step 6:

Place the 3d printed "wheel" on the shaft of the Jameco motor.

Step 7:

Make a lily pad and frogs using clay. Bake the frogs. Glue the assembly to the rotating base.

Step 8:

Take a .44 inch by 10.25 inch by .04 inch spring and cut it in half.

Insert each half in a 3d printed spring holder--tilting the spring at an angle.

Glue clay frogs on the ends and screw the holders to the top of the box.
