DJ Big Gulp - Floating Bluetooth Speaker

I transformed a Gatorade jug into a floating bluetooth speaker for river tubing.  Check out my blog post for the full story!

Materials

• Main body
  • Igloo Sport 1/2 Gallon Jug With Hooks
  • Pioneer 5-1/4" Speaker
  • 12V SLA Battery
  • Marine weather stripping
  • Amplifier Enclosure
    • Bluetooth Amplifier Board
    • 4 Pan head screw 8-32 3/8"
    • 4 Pan head screw M3 x 0.5 mm Thread, 5 mm Long
    • 4 Heat-Set Inserts for Plastic, Brass, 8-32 Thread Size, 1/4" Installed Length
    • 4 Heat-Set Inserts for Plastic, Brass, M3 x 0.5 mm, 4.3 mm Installed Length
    • 3D-printed “DAMGOO Enclosure Cover”
    • 3D-printed “DAMGOO Enclosure Base”
  • Wire
  • Spade connectors
  • Velcro strips (to hold battery)
  • 3D-printed “DJ Big Gulp Lid”
• Flotation
  • Roughly 10' of 1/2" Schedule 40 CPVC pipe (0.62" OD to fit into bracket)
  • 8 45° elbows
  • 4 Tee fittings
  • Pool noodle
  • 3D-printed “DJ Big Gulp 4 Leg Bracket”

Printing Tips

• 0.2mm layer height and 15% infill should be fine
• No supports needed except for “DAMGOO Enclosure Cover” - print it with the hump touching the build plate

Assembly Tips

• Cut the mounting tabs off the speaker - I used a Dremel
• Attach the marine weather stripping about ¾" from the top of the opening, just above where the contour of the inside changes
• The PVC legs connect to the bracket at a 35° angle - only one combination of leg length and base perimeter will satisfy this requirement. I'd suggest dry fitting first and trimming if necessary.  My legs are about 10" long.
• The main body isn't permanently attached to the flotation frame.  You might need to apply a little duct tape to the main body so that there's enough friction to keep it from slipping out when you pick it up by the handle
