Passive Mixer Enclosure

This chinese stereo audio mixer from aliexpress comes only semi-enclosed, i've designed this bezel to cover the openings.
Designed this to reuse all hardware that comes with mixer.
No supports needed.
I don't use brim to eliminate post-processing, but had to be carefull with adhesion. After failed print it helped to increase bed temp...
I like to print with bit of fuzzy skin, but your taste might vary.
I wasn't smart enough to be able to design this as single part, so it has to be assembled. Maybe someone will suggest some trick to allow single piece seamless design?

Mixer has no brand, but can be found online as "4 channel passive audio mixer". It came with manual that says it's "TX400" series, but i am not sure... Might be TM400, TP400 or something completely else... Since it's passive, you shoud expect around 50% decrese of volume.
