Wireless Phone Charger – 3D Printing Build


This is a super easy and useful build. I saw this Qi wireless charger on adafruit.com and decided to design a 3D printed enclosure for it. It’s a relatively quick print and easy assembly and obviously very functional if you have a compatible phone!

What You Will Need

Any/all necessary protective equipment.

3D Printed Parts

(~6 hours @ 60 mm/s)

  • Filament choice not all that important. I used ABS which was easy to sand and paint.
  • 0.2mm layer height.
  • 25% infill.
  • Support not required.

Finishing 3D Printed Parts

  1. Remove any support material if it was used.
  2. Sand the printed parts using 150 – 400 grit sandpaper until smooth.
  3. Use Bondo spot putty to fill in any remaining surface defects. Once dry, sand until smooth.
  4. Using a lightly damp cloth, wipe down sanded parts to remove any dust.
  5. Apply 1-2 coats of primer.
  6. Lightly sand down dry primed parts with 600+ grit sandpaper
  7. Using a lightly damp cloth, wipe down sanded parts to remove any dust
  8. Apply 2-3 coats of spray paint to the two outer pieces. Let dry.
  9. Apply 1-2 coats of clear coat.

Assemble the Charger

  1. Start by placing the top of the charger upside down. Insert the wireless charging base plate into the cavity with the coil facing downward (pointing toward your phone when oriented correctly).
  2. The add the 3D printed plate on top of the charging base plate with the notches pointed up toward you as you assemble. Optionally you can glue this into place.
  3. Finally add the PCB board with the ports facing outward in their respective slots.
  4. Glue the base to the top.
  5. Plug in a micro USB charger and enjoy!


Thanks for taking the time to explore the project, I hope you try it and if you do I’d love to hear your feedback and see pictures of your build!
