Ampi is an iPhone sound amplifier and son of an empty toilet paper roll, its birth being a moment
of pure and raw improvisation on a workbench.
Its cylindrical shape comes from the original model, made up of an empty toilet paper roll with a slit on one end and an iPhone shoved into it. From there, the concept evolved, and by adding stability and an opening on the back for the charging cable, Ampi transformed into a proper phone stand.
°iPhone 6 3D model was done by Jeffrey Popowski and can be found on GrabCAD | renderings on this post of such iPhone were done by me.
