A maker dad sets to work repairing (and improving) a broken toy and shares his process of 3D printing replacement parts for it:
This is one of those really cheap toys that makes more noise that it actually does things.
It has only 1 motor at the back, the front wheels don’t even touch the ground and to turn it actually goes backwards which blocks one wheel and allows only the other one to move, hence always turning in the same direction (this is sooooo annoying ! ).
Anyhow, as any father that has nothing else to do and was looking for an excuse to do something with my underused 3D printer, I set up on fixing it….
It might be worth mentioning that I used:
- Inkscape to draw the gears (really great tool) and the complex shapes of the motor mounts
- OpenSCAD to extrude the drawings from Inkscape into shapes and export to STL
- Cura to generate the GCODE from STL and do the printing
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
