Endor amplifier housing and Nomoon speaker

Casing for TDA7492P. I have only designed the Amplifier casing the nomone speaker is from this link https://www.thingiverse.com/thing:590871
I have generated it to fit this speaker https://bekent.dk/sph-2m.html and the guy's from bekent.dk calculated the volume of the speaker and size of the bass reflex tube, they are super nice and helpful. I also designed the ring to fixate the speaker.
The amplifier is fitted to the casing with the feat it comes with i was just able to squeeze then down i
