Corner Wall Mount for TCL Q85H Pro-RS Speaker

This mount angles the speaker downward around 28 degrees, and inward around 26 degrees.  

Mirror the part to print a complimentary Left Rear version 

You could use the model as Left rear, and a mirrored version for Right Rear to point it at the complimentary angle inward.

I used 4mm*50mm drywall screws to screw it into the wall.  The screw holes are 4mm diameter with a chamfered top to suit screws up to 12mm or so head diameter flush.

The power cable for the speaker fits behind the mount in the corner.

Some of the photos are of the MK1 version, which had a slightly steeper bottom angle and only 2 screw mount holes.  Otherwise all the critical dimensions are similar.

I printed this at 0.2mm in PETG HF Grey on a Bambu P2S with no supports
