Does anyone here have a 3d printer?

    I've fitted some new tweeters in the car, and I'm worried about them being damaged because the two protection bars don't offer much protection to the soft dome.

    Could someone 3d print a pair of grills for me? I'd be happy to pay for your time, materials and postage.

    The tweeters are Vifa NE25VTS-04 - https://products.peerless-audio.com/transducer/120

    Think I'm going to buy one of these - Creality 3D Ender-3 - Seems pretty good value under £150.

    Watching Fusion 360 tutorials now...

    You will find loads of other uses for it I'm sure

    I quite like the challenge of learning new things, so it's perhaps a good thing no one offered to help (although I just had an offer through PM).

    I've managed to model what looks like a camera lens end cap, just need to work out how to put holes in the face. I can put one 3mm hole in, but obviously it needs lots of holes...

    Mk1 tweeter grill. Don't laugh, lots of swearing went into this.

    You can have the holes go all the way to the edge but just make the hole depth equal to the thickness of the part. Also, I bet you can figure out how to make the part domed instead of flat!

    I bet you’ll enjoy the printer, and it’s good you’re learning CAD first. Fusion 360 is great.

    I’ve been selling parts for vintage Sansuis on eBay this year. Already made a few thousand in sales! Not bad for a side hustle.

    Yes, the ideal scenario would be domed, holes only to the depth of the material and the honeycomb lined up better. I would also like fixing holes that line up with the ones in the tweeter, so I don't have to make it like a camera lens cap. Going to have to watch more tutorials...

    I did search for tweeter grills but mine aren't flush mounted, so the grill has to be a perfect fit.

    Thanks Gary, I'll look at that thingiverse place when I have time...

    Great first effort! If you put some triangular holes between the hexagons, you have B&W’s tweeter grille pattern, or thereabouts!

    I’m not a Fusion 360 user, but if you want a dome have a look for a ‘revolve’ feature or similar.

    You should be able to select the rear face in the extrude or ‘hole’ feature you’re using for the hexagon cutouts as a reference for the depth. This gives you a robust way to constrain your feature, i.e. if you change the thickness of the part, the hole cutouts will update and always cut through as you intended.
