Machines Used

• Taz Lulzbot Mini 2
• https://lulzbot.com/store/lulzbot-mini-v2-0-boxed-for-retail-na-kt-pr0047na
• Universal 3.60 Laser Cutter

First, we put together our circuit.

• We tried to use minimal soldering until we got the wiring right.

We 3d printed the casing for the 3d speaker using the Taz Lulzbot Mini 2.

Afterwards, we laser cut circular shapes to fit to the sides of the casing.

• Files are included below.

The wood circular pieces go on the outside of the speaker and should fit snugly. Apply hot glue to the corners of the wood pieces and the speakers to keep them inplace.

We made sure our circuit worked then finalized it by sawdering.

• Make sure while soldering you leave one speaker un-soldered and both the switch and charging port un-soldered until they are in the correct spots.
• Insert components into the speaker casing. Pull the wires that go to the switch and charging port through the corresponding holes. Solder the wires to the switch and the correct wires to the charging port. Then insert the switch and charging port into the case. This might require sanding.
• After you insert the charging port use the included nut to keep the charging port snug.
• Proceed to pull the wiring through the casing that connects to the un-soldered speaker. Solder the speaker to the correct wires.
• Press both speakers into the casing.

Finally, it is time to create the wood stand pieces that the speaker lies on. To do this, we laser cut pieces for the speaker to lay on. Putting the pieces together might require sanding. Those files are included below.
