3D model description

This design should still be considered experimental. I'm uploading it because folks have asked, but I have not yet tested it thoroughly.

I designed this to use for the MAME arcade cabinet I'm building. The "base" should screw directly into the face of the speaker box and into the portion of the cabinet that frames the speaker. The "grille" should then (in theory) snap into place on top of the base. While it should hopefully be removable, I can't speak to how frequently it can be placed and removed without damage.

The following instructions are for Cura. I'd imagine you can do something similar in other slicers, but I can't offer precise steps.

The "reinforcement" is a (possibly optional?) bit to strengthen the part of the base that is screwed. To use it, you'll want to center both the base and the reinforcement on the build plate at the same time. From the left sidebar, change the settings specifically for the reinforcement to "Modify settings for overlaps" and "Infill mesh only." Although you should supposedly be able to then change the infill density, I wasn't able to do that for some reason, so I ended up changing the wall line count to 14, which had more-or-less the same effect.

For printing the "grille," note that it is modeled as a solid piece. If you just print it as is, there will be no holes for the sound to pass through. I did this on purpose to both save myself some hassle and allow for greater customization.

Set the top and bottom layers of the "grille" to 0. Then set the infill to any pattern that continues directly through from top to bottom. (I used "Triangles.") Set the density such that the holes are not too small for the sound to easily pass through, but you'll also need to make sure they're not too big that they don't support the snap connectors at the corners. (I set it to 6.35 mm.) I also increased the infill layer thickness to 0.2, and you might want to up the wall count by a bit.

Alternatively, feel free to take the solid grille and use it as a template from which to cut out whatever designed sound holes you would like.

Printing on my Ender 3, I had to rotate these models 90 degrees to get Cura to accept that they would fit (even though in theory they're smaller than the build area in either direction). And turn off any build plate adhesion.

As always, if you enjoy this design, feel free to tip me a coffee!
