A bit of bronze rub'n'buff and voilà. Printed on A1 mini with max scale to 16cm internal width from hole-to-hole that closer to ears. I was required to turn it on a side to fit into a1 mini. Things to improve: 1. The mouth hole quite too low, when wearing you can see the bottom teeth only which looks weird. 2. Top holes for mounting stripe place under the ears, maybe makes sense to move them to the top for keeping the stripes over the ears. *3. Can't wear it with AirPods-like headphones 😅.
