Check out how to switch adapt this Jack-in-the-Box. A person with disabilities can now use their AT switch to turn the crank of this beloved toy and make “Jack” pop out!

This design has a curved based at the bottom to allow view of the pictures on each side of the box. The bottom of the box is left open to save 3-D printing time and filament.

Materials:

• Standard Schylling Jack-in-the-Box
• 3-D Printed “Base Mount” for motor and box and 3-D Printed “Knob Mount” (at Thingiverse.com)
• Small DC motor in servo housing
• 3.5mm Panel Mount Jack  to plug in switch
• Screw and washer to hold down knob mount
• Poster Tack (Ticky Tack) holds toy in place
• Batteries AAA or AA (Power 4.5-5 Volts)
• Drill to make hole for jack
• Switch for testing

Steps:

1. 3-D Print pieces: “Base Mount” for motor and box and “Knob Mount”. 

2. Drill Holes for jack for switch and for power to batteries. (Notice error in that we drilled holes across from each other, not leaving enough room for both the power jack and the jack for the switch. If you make either hole too high, it may be difficult to run wires.)

3. Attach small DC motor on arm of base mount and run wires down shaft. Hole in bottom helps to wire motor and then tuck the wires inside.

4. Wire switch jack and power jack (or battery pack) to DC motor.

5. Plug in a switch to test that motor turns. When switch is closed, contact is closed to turn motor.

6. Insert Jack in the box in base mount and knob in the knob mount. Use poster tack to hold box in mount if needed.

7. Plug in the switch and have fun!
