Honda Acty Speaker Grommets / Screw Inserts

Made this remix based on a 7mm square hole grommet to fit speakers into my Honda Acty V-HA3. These grommets can easily be bought on AliExpress and Amazon but we have these 3D printers for a reason, don't we!? 

These grommets support 4mm (wood) screws, I would suggest a max length of 40mm. This ensures that it doesn't scratch the window when it's rolled down.

I used this speaker adapter to fit 16,5" round speakers into the 13" square hole. It fits these speaker models, your mileage may vary.
The original creator designed these for the 6.5" Kenwood KFC-1666S speakers.
Since I'm based in europe and those speakers weren't available near me, I used the 6.5 Kenwood KFCS1676EX which also fits.

I created 5mm TPU spacers using this model in between the spacers, grommets and speaker adapter to avoid rattling.

Would definitely recommend printing this in something that is somewhat heat resistant like (dried out before printing) PETG. Since these grommets are really narrow, please use the brim which is set in the profile.
