desktop speaker

thingiverse

Small 3d printed desktop speakers inspired by the Cambridge Audio Minx Min. Had general idea of the size and frequency response I wanted. Headed over to Parts Express and settled on the Tectonic BMR 3″ Full-Range speaker for about ~$20 each. No audiophile here, but they sound pretty good to me for such a small speaker. Have not measured these, but guessing they cut out around 120Hz or so based on YouTube speaker frequency “tests”. Being so small you really can’t expect a lot of bass. Enclosure does vibrate a bit, especially as I turn up the volume. I printed on an Ender 3 pro with 6mm nozzle using mostly the suggested setting for Standard Quality 0.2mm in CURA. Added a brim for added protection and think I increased walls and bottom layers. I oriented the parts so that the back of each piece was on the bed. This way you dont need any supports. I used spray primer/filler, lots of sanding and black spray paint. Binding posts are from PartsExpress and used some misc hardware (bolts, washers, nuts) from hardware store to assemble. Note that 3rd hole on back of body is for a bolt to mount to wall or on a speaker stand.
