I HAVE MOVED ALL MY DESIGNS TO MY OWN SITE http://www.tmophoto.com/product-category/3d-product-download/
.i modified the original by making the cone snap in and out as well as chopping off the hard corners.
print it with exterior support
this is still a work in progress, it works but i can make it better
the large cone i printed failed half way through so i glued it to another cone i had to make a super mega phone cone.
the straight one with the small cone is pretty damn loud i drilled out the hole so its not the correct size for slip in fit.
this is a video of the sound difference
print one cone and one holder
small cone works really well
large cone is untested fully, my print failed half way through
"iphone speaker stand" shoots the music out in the direction of the screen and must be printed with external support turned on
iphone bottom straight shoots the music straight out the bottom. the hole will need to be drilled out with a 3/8" drill bit
they work incredibly well
