Taranis X9D 40mm Speaker Cup

i made this a while back not sure if this is the lasted version.
the tall was made to prevent touching the speaker inside but then i designed a cover that didn't fit. you could leave the pin in place but i broke them off and installed the cover.

This is the speaker i used
