Phone pouch

I sometimes want to talk on the phone while keeping both hands free but don't have ear buds available. So I designed a slightly oversize pouch that I could hang around my neck and slip the phone into. The ear file is provided because I didn't think the wall of the pouch would safely support the phone.The ears are glued on the pouch with silicone adhesive. My pouch was printed with TPU but a rigid filament should work too. Any kind of lanyard material will work.
