Printable speaker ring for audio projects. I've printed mine without bottom layers and after i filled it with resin. No issues so far. Designed to fit Pride Diamond 8 V2, but they should fit many other speakers (tested also with Rockville RXM 84).

Print with PLA or ABS if you plan on using it with resin. Resin doesn't stick to PETG that well. Stronger materials are prefered.

There are two models, one is slightly cut off on sides to fit printbed of Ender 3. This one could also be used if you are planning to put multiple speakers next to each other. That way it's a lot easier to line them up.
