3D Print Speaker Box

3D Print Mr. Meeseeks box. STL file is in introduction.

Test Connection

Test speakers and bluetooth board to see if they connect. Connect them to a bread board and wire them correctly to power them.

Solder Power Switch

Solder one wire from each port. One wire connects to the 5V power on the bottom of the bluetooth board. The other connects to the outside positive output on the blue charging module.

Solder Charging Port

There should be 2 wires coming from the charging port. The positive (red) wire connects to the large hole on the port and the other end connects to the positive port on the blue charging module (USB side). The negative (black) wire connects to the higher hole on the charging port. The other end of the negative wire connects to the negative port on the blue charging module (USB side).

Solder Bluetooth Board and Charging Module

Only one wire is needed to connect the bluetooth board and charging module together. That wire will be a negative (black) connection. One end of the wire connects to the bottom of the bluetooth board in the GND hole, while the other end connects to the charging module in the outside negative out hole (same side as power switch connection).

Solder Battery to Charging Module

Strip the battery wires to connect to charging module. Connect the negative (black) wire to the inside negative hole (next to bluetooth board connection) and the positive (red) wire to the inside positive hole (next to power switch connection).

Solder Speakers to Adapter

Strip the speaker wires to connect to the adapter. Both speakers have positive and negative wires but they all go to different colored wires. One speaker will connect matching wires (red to red, black to black). The other will connect the red wire to the white wire, and the black wire to the yellow wire. Attach the adapter to the bluetooth board through the correct connector.

Screw in Speaker

Cut holes in the box to fit the speaker. The holes should be on opposite sides of each other. Drill a hole in the box that line up with the speaker bolt holes and screw in the speakers.

Connect Charging Port and Power Switch

Cut a hole that fits the given size of the charging port into the lid of the speaker. Insert the charging port and secure it with a nut. On the opposite side of the charging port, cut out a rectangle that fits the size of the power switch. Apply super glue to the sides of the switch and secure it in the hole.

Stuff the Box

Stuff all the connected wires and battery into the box and insert the lid. The lid should be able to be opened just in case of any soldering errors.
