Wall Mount for Monolith by Monoprice MM-3

I designed these to wall mount my speakers in a low profile way. Frankly I want to redesign these; however, they have been working.

Also seen in the pictures, are some models not designed by me: the honeycomb wall. And some accessories to the honeycomb wall that I did design (the edge cable routing, the hooks, the tray, and the thrustmaster throttle mount). I'll include a link to the cable routing as it is related to the speaker mount: https://makerworld.com/en/models/209176#profileId-229089
