SparkFun Audio Amplifier Enclosure

thingiverse

SparkFun offers a straightforward audio amplifier kit called STA540 (https://www.sparkfun.com/products/9612). As I plan to construct numerous units and enhance their automation, I needed an enclosure for these devices. To keep them out of sight and mind, hidden under my desk and other places, I also included mounting tabs in the design. However, this design is not complete, as a cover is yet to be added. As of August 2012, the kit functions and fits as supplied by SparkFun. To assemble, print the standoffs designed for M3x20mm bolts with hex nut captures in the bottom. You will need 4x(M3x20mm) bolts and 4x(M3 hex nuts) for mounting. There might be some droop when transitioning from printing a hex nut capture to the shaft opening for the M3 bolt, but an exact-o knife can easily fix this issue.
