HK 19.5 under-cabinet mounting bracket

thingiverse

These old Harman Kardon 19.5 computer speakers are among the best ever made in this form factor, even after nearly 20 years have passed. Since I had both of them and a Chromecast Audio sitting around in a box, I decided that was as good an excuse as any to extend my home audio system into the kitchen. (No, that's not the Chromecast in the photo ... Wouldn't it be nice if those Minis actually had a headphone jack?) **Instructions:** - Print the speaker side such that the tip of the tail hook rests on the print bed (this is "upside down" from how the STL usually loads). I recommend using a brim because the hook tends to come unstuck during printing, and appropriate support material should be used. - Print the bracket however you want, though I chose to do so with support under the "screw wings" so the part that slides against the speaker side of the bracket gets the best surface. It also does better with support material. - Using the speaker bracket as a template, drill into the bottom of the speaker (carefully, especially on the "right" speaker which has electronics close to the bottom plastic) and tap for m3 screws. I used m3-5mm on most, and m3-4mm on the two spots at the rear or the right speaker, just to be safe. - Mount under cabinets or wherever you want them to go using appropriate screws (I used #6 x 3/4").
