Amplifier Box for PAM8406

I bought these small chip amplifiers on Amazon - https://www.amazon.com/dp/B08RDN58SZ?psc=1&ref=ppx_yo2ov_dt_b_product_details

They sound pretty nice for situations that can tolerate the low power (near field, small space, very efficient speakers). So I thought I'd try to design and 3D print a box for them, and it worked pretty well.

I'm using the following connectors, but these are mostly standard dimensions so I would expect substitutions to be easy.
In -> RCA plugs - https://www.amazon.com/dp/B07DH77ZB8?psc=1&ref=ppx_yo2ov_dt_b_product_details
Out -> binding posts - https://www.amazon.com/dp/B07CK1VL3B?psc=1&ref=ppx_yo2ov_dt_b_product_details
Board input is 3.5mm jack, so RCA -> 3.5mm -> board - https://www.amazon.com/dp/B077XNTSF9?psc=1&ref=ppx_yo2ov_dt_b_product_details
Power - 5.5mm panel mount barrel jack - https://www.amazon.com/dp/B091PS6XQ4?psc=1&ref=ppx_yo2ov_dt_b_product_details
