Cowboy bike - Adapter for Kokox smartphone holder

thingiverse

The Kokox Smartphone holder is an excellent product. It is easy to install and use. I bought one in 2020. Between the two available models I chose the one for larger smartphones. A few months ago I downgraded to a compact Google Pixel 4a. Even with protection case it is too small for the Kokox holder. The light brown adapter fills the gap. You can attach it with double-sided adhesive tape. An even better solution would be to print it in TPU or use flat rubber rings. I use rings stripped off a broken RealFx racing toy car. The rubbery surface has better grip on the phone. The enclosed adapter size should work for most phones. If you need to customize it use the enclosed .step file.
