I created this thing for the telephone in my office, which uses the reciever microphone when using the hands-free speaking system (at least if you talk into the receiver the voice quality is much better). The stand works for receivers with a width of 50mm. If yours is different, I have included the 123D source files so it should be possible to adjust the thing accordingly.I printed on an UItimaker 2 with PLA and the following settings: Layer height: 0.25mm Shell thickness: 0.8mm Retraction enabled Bottom/Top thickness: 0.6mm Fill Density: 20% Print speed: 50mm/s Support type: none Platform adhesion type: brim
