Gather the mini oval speaker and 3d printed case. Locate the spot inside the case for the speaker – It has several holes and two raised edges. The speaker will be fitted in this spot.
The mini oval speaker should have a loose fit. Instead of a friction fit, we'll "stick" it to the surface.
Remove Sticker Backing
Peel the protective backing from the speaker. Handle with caution to avoid accidentally dropping.
Get the speaker inside the case and position it so it's directly over the spot. Note: The wire is pointing away from the holes. Carefully reposition and adjust so the speaker is lined up as close as possible. Reference the photo as needed. Press firmly to adhere the speaker to the case.
The speaker cable has just enough length to reach the audio out port on the Prop-Maker FeatherWing.
