Super73 Drop-In Holster for Bose SoundLink Revolve

I designed this custom drop-in holster to mount a Bose SoundLink Revolve speaker directly to my Super73 RX. If you want to listen to music while riding and need a mount that can handle high speeds, heavy bumps, and vibrations, this is it.

The mount bolts right to the Super73 Molle panel using standard 65mm spacing (the same spacing as a water bottle cage, so it fits a lot of other bikes too). The back spine is a thick, solid block for maximum strength. The middle has a huge cutout so the speaker grille stays wide open and your music does not sound muffled. I also gave it a solid floor with a 5mm water drain hole, just in case you get caught in the rain or wash your bike.

Hardware Needed

• 2x M5 x 20mm screws: Socket head or button head screws look the best.

• 2x M5 metal washers: You absolutely need to put washers under the screw heads so you do not crush and crack the plastic when you tighten them down.

• Sticky foam tape: The inside of the mount is a straight tube, but the top of the Bose speaker is tapered. Stick a strip of weather stripping or foam tape inside the top ring of the mount. This fills the gap and totally stops the speaker from rattling while you ride.

Print Settings I print this on my Creality K2 Combo using PETG filament, so it easily survives the hot San Jose summer sun without warping or melting. PETG is a good backup, but definitely do not use PLA for a bike mount.

• Orientation: Print it laying completely flat on the thick back spine. This is the most important step. It makes the layer lines run up and down the length of the mount, preventing them from snapping off your frame.

• Walls/Perimeters: 6 walls. This makes the mounting slots and the main body super tough.

• Infill: 30% to 40% Gyroid.

• Supports: Turn on normal supports. Since it prints laying on its back, the printer will need to build some supports to hold up the top and bottom rings.
