Phone stand folded speaker horn

Phone stand folded speaker horn

Description

This passive speaker phone stand really amplifies the sound quite significantly. Even without the insert. High frequencies more so than low frequencies. I tried to increase the surface area of the horn exponentially to get the most amplifiction. But my modelling skills (and math) let me down a bit. But I am still quite satisfied with the result for a first attempt. Any tips on how to improve the design are much welcome! The model fits my mi-A1 with phone case: thing:3044340 There is an insert with a .5mm gap and one with .6mm gap. .5mm worked for me, but it took some sanding and a bit of brute force to assemble.
