hello, this is my first thing! My idea was the fact, that an human ear probably is the best shape for sound input. It has, after all, took millions of years to develop this thing. ok, if your an creationist, you don't believe that fact ;-) so why the ear shape should not be good as an speaker. Moreover, my tablet only got one speaker on the back, which is often too quiet. i am amazed at how well the new ear on my tablet works! the tablet is definitely louder and looks fabulous in my opinion (if you like the natural style)! PS: the original human ear is from tpower118, published Jun 19, 2013 on thingiverse (http://www.thingiverse.com/thing:105808). hey tpower118, thanks for your work! PS: this is also an entry on the 3d-printing contest on instructables: PLEASE VOTE! http://www.instructables.com/contest/3dprintingcontestxxl/i use PLA with the following printing settings: Supports: yes Raft: yes Infill: 70% (less likely works as well) Shells: 2 the other settings such as printing speed and layer thickness depends on the capabilities of your printer. To remove the print from the printing plate* I take the good old carpenter chisel. this is definitely the best tool for doing this. the chisel is an good tool to remove the supports an clean the print too! make sure that the chisel is keen, otherwise you don't have fun with it.
