Ikea Symfonisk Speaker Wall Mount
Toolless and no hardware assembly, optional filament channels used to lock in place.
I designed this after struggling to find a design that didn't require nuts/bolts, didn't required 8 hours of print time, and seemed robust enough to be wall mounted.
All parts for 1 speaker print on a single plate in about 4 hours. Brim is recommended due to large flat surfaces prone to warping. Only one section requires minor bridging and it is hidden after assembly. Tolerances are pretty tight to ensure a stable fit.
3 wall loops for strength
Suggest 3+ bottom/top solid layers
15-35% infill
Suggest ABS/ASA but will probably work with other filaments
Left/Right angle is adjustable in 22.5deg increments
Up/Down angle is selectable at 1deg, 18deg, or 30deg - can add additional variants if needed
