Speaker Bracket (Edifier R1280DB and similar)

Speaker Bracket (Edifier R1280DB and similar)

A wall or corner-mounted speaker bracket designed around the Edifier R1280DB but compatible with any speaker no wider than it (else it will touch the walls on the side). Speaker faces 30° down and 45° away from the wall it is attached to. A clevis at the top carries the load (the yoke piece screws to the top of the speaker and drops into a slot on the bracket), and a saddle at the bottom catches the speaker to redistribute weight in case the print sags over time. The bracket attaches to the wall via two "ears" at the back. Because the bracket itself is flat, each ear is sandwiched by a small pinch piece (printed alongside the bracket) with a screw clamping the assembly through both. The pinch piece does double duty: backing block for the screw on one side, 45° wedge on the other.

Standoffs for a Raspberry Pi Zero are baked into the side of the bracket, and there are zip-tie notches around the frame for cable management.

Note for corner installs: walls are rarely flat right at the corner — they tend to round off — which can tip the assembly off-axis and let a corner of the speaker touch the wall. If that happens, shim the pinch block to bring the bracket back to 45° from the wall.

Assembly note

Screw the yoke to the back of your speaker at whatever height makes the bottom of the speaker barely meet the saddle. You don't have to get it exactly right, the saddle is not meant to take the load. It's just a safety in case the frame sags.

On the R1280DB, the yoke is meant to be flush with the top.

Why I made it

I couldn't find any bracket that mounts a bookshelf speaker invisibly. This one does — once the speaker is in place the only visible piece is the saddle at the bottom, and even that could be remixed out since the clevis carries the full weight on its own.

Printing notes

• Reinforced filament strongly recommended. I printed mine in ABS-GF and that's what I recommend. Fiber reinforcement helps with sag over time and allows for a more precise print which helps with the tight tolerances on this one.

• Supports required, but minimized — check the included print profile

• All parts exported in the optimal orientation (the clevis yoke is debatable but it's a good tradeoff, test your part if you doubt your layer bonding)

Foot notes

• I always include STEP files to make remixing or just playing around with my models easier. If you see them missing please let me know and I will add them!

• One day, filament recycling will be viable. This is why I always deboss material names on an inconspicuous face of my models and I encourage you to do the same. When you will no longer have a use for the part you print today, if by then recycling made it to or near our homes, you will know for sure what it was printed out of.
