I designed this holder for a walker with a textile backrest.
The space for the phone is 90mm*17mm and was made for a standard phone with silicon backcover, the phone is ca. ⅔ of its length inside the holder.
The gap for the fabric is 5mm wide.
Printed with 4 walls for more stability.
My first holder was made from PLA and was broken after a few months of daily using. So I added two ribs and and a fillet radius on the weak place. And I printed the new version using TPU.
The author marked this model as their own original creation.
