I wanted to have my old kiox 300 usable with the smartphonegrip. And I just did not want to have 2 holders on my steer. So I added a normal holder for my kiox on the left of my 90 degrees holder.

My Xiaomi 14 fits perfect for this. If you need bigger space or smaller, tell me, and I'll create the model and upload the profile for it.

As the normal kiox 90 degrees adapter, you also need 2 ruthex insets

The photo assembled on my bike is printed with very old filament, but worked anyway. I printed it in gray PLA also to show it's nice with new filament.

I did 2 variants for this. 

V1 - Kiox left (additional 150mm Bosch connection cable needed) (black on the fotos and print profile)

V2 - Kiox right (additional 100mm Bosch connection cable needed) (gray on the fotos and print profile)
