Phone holder thin base (lining insert)

thingiverse

I've decided to go a different route for my car phone holder design. This new version reuses a commercial universal wireless charger that's both affordable (~5 USD) and easy to install. I replaced the original ball with a custom one, which fits perfectly inside the dashboard lining. The lining can be easily spread using a thin card or special automotive tools. If you obtain a flat micro USB cable, you can route it inside the car up to the phone holder as well. I won't provide a direct link to the charger, but I purchased it from AliExpress under the title "FDGAO 10W Qi Wireless Car Charger". Design Details -------------- You can access my design on OnShape at https://cad.onshape.com/documents/41200c8734a10209bbe3f9c8/w/74b349638e2834f45c5e729f/e/2aa0005addc5f76d74ed18c4. The ball/socket size is 17mm, so you can either edit the design in OnShape for different sizes or try scaling my design. The insert has small protrusions to help with adhesion and prevent it from slipping around too much. It's 2mm thick, which I found provides a good balance between flexibility and stability. I've tried using thinner materials before, but they tend to flex excessively. Printing Details ---------------- I printed the object with 25% infill in white PETG, but you can use PLA as well. The layer height is set at 0.25mm, and supports and rafts were enabled during printing. Make sure to rotate the object with the ball facing down before printing for optimal results.
