Bluetooth Speaker for under $150

A large 3D Printed bluetooth speaker. It sounds pretty good, and can be made for less than $150 including all the printer filament.

(I've also used this with a Spotify connect raspberry pi zero W instead of the Bluetooth internals so feel free to do that if you prefer that to Bluetooth)

This design is based on the Concrete Bluetooth Speaker By Matt at DIYPerks but of course all the enclosure design is 100% from scratch. https://www.youtube.com/watch?v=a43LXqRwQC8

Leave a comment if you'd like a full assembly/build guide.

For the four main body parts, Print with the largest nozzle you can with big line widths, no need to go crazy on the infill, 10% is fine. You could do it with a small nozzle, it'll just take forever.

For the TPU seal, keep the infill fairly low, around 5%, and use gyroid infill or any other 3D infill, this is to ensure it can compress in the Z direction.

For the Face plate print it face up and go for a standard size nozzle in order to get the best possible finish. It would probably be pretty easy to sand it down smooth if you're into that sort of thing.

For the thin vanity piece do what you like, go crazy. I just blue-tacked mine on in the end but don't really like it so tend to go without.

For the shell, go for big nozzle and line width again. Turn on Vase mode print. You don't have to, but it saves layer change and retraction etc.

For the electronics tray and mount, standard .4 nozzle and any infill probably fine.
