quarter wave phone stand/amplifier
Description
Had some interest in the quarter wave amplifier and wanted a small version for a phone. I am not well versed on all of the specifics of a true quarter wave acoustic device but this is definitely louder than my bell shaped phone amplifier. Print at 45 degree angle and set support structure to 85 degrees. This way there will be no internal supports to remove and the only support needed is the bridge area under where the phone is placed.The piece on the back is only to help it stay seated at 45 degrees while printing. Print this the same way it loads on your slicer. I also used a raft for extra support while printing but that may not be necessary. Dimensions for phone are 85mm x 13.5mm. Most phones with a bumper case should work. I plan on making a version to fit an otter box plus sized phone as well and may increase the bell size. update: 11/20 larger bell opening. update: 11/21 added rearward piece for stability
