RC-Car Joystick/controller

Lately I purchased a budget-friendly RC Car, specifically the model "Crawler Car," from Lidl in Germany. https://www.lidl.de/de/rc-fahrzeug/p288149?searchTrackingQuery=RC%20CAR&searchTrackingId=Product.288149&searchTrackingPos=2&searchTrackingOrigPos=3&searchTrackingRelevancy=90.42&searchTrackingPage=1&searchTrackingPageSize=36&searchTrackingOrigPageSize=36 I was extremely frustrated because controlling the car with its original controller proved challenging for me, and even more so for my kid. So I designed a simple controller that makes it easy to control the car. Print one piece of each part and two pieces of "button" and "button-holder". I utilized the following components from the original controller: -- 6 screws -- Battery holder -- The circuit board, of course -- On/off switch Instructions: 1. Open the original controller. 2. Remove the circuit board, battery holder, on/off-switch, and 6 screws from it. 3. You will need four standard push buttons, which you can desolder from the original circuit board (or any other old board with buttons). 4. Solder wires to the push-buttons. 5. Insert the push-buttons into the "button-holder" and "button-holder-arrow". 6. Insert the printed "button" and "arrow-key" into the "top" part. 7. Press the "button-holder" and "button-holder-arrow" to secure the buttons. Depending on your printer, you may need to use sandpaper to trim these parts. I recommend using hot glue to secure these parts, even if they fit exactly. Don't forget to apply hot glue to the soldered wires as well. 8. Secure the circuit board to the top part with three screws. Place the LED in the top hole and the ON/OFF switch in its designated spot. 9. Solder the button wires to the circuit board. Use hot glue to secure the wires. 10. Hot glue and fix the battery holder to the printed "down" part. 11. Use the remaining three screws to join the "down" and "top" parts together.
