Speaker housing 2.5" for YAESU 991A or 991

I wanted to create a housing for the Peerless by Tymphany PLS-P830984 Speaker to use it next to my Yaesu FT991A. The Yaesu SP10 for 100 bucks seems to be very bad so I researched and bought that speaker.

Its an easy box, definitely much room for improvement, but I am still learning how to create things on my own :)
