Phone stand folded speaker horn

cults3d

I built this speaker phone stand to make sound more powerful. It really works well even without the extra part. High sounds get amplified more than low sounds. I tried to make the horn part bigger to get the best results, but my math skills are not strong enough. Still, I'm happy with how it turned out for a first try. If you have any ideas on how to make it better, please share them! This design fits well with my mi-A1 phone and case (thing number 3044340). There's an extra part that helps fit the phone in tightly. It has two different sizes: .5mm and .6mm gaps. I used .5mm, but it took some sanding to get it just right and a bit of force to put it together.
