Full credit goes to @benoit_955624 over on Printables. This is a remix of one of their parts - https://www.printables.com/model/983715-angle-bracket-for-sony-ht-mt301-soundbar

Angle bracket for the Klipsch Flexus Core 100 soundbar to orient the soundbar towards the user when used on a desktop.

Bonus, it allows the cable to go under the soundbar like the one for my keyboard.

To get the honeycomb look: Print object on the largest flat side No top or bottom layer 10-20% honeycomb infill (object is plenty strong at 10% infill, up to user preference) 2-3 walls
