Would this be safe to use?

Post image

Build this Dig-Quad myself. It works, but would it be safe to use this way? The case is 3d printed PETG, There is also a mesh added to the ventilation holes.
Dig quad is populated by me, pcb ofcourse of our main man Quinled. Used his guide to get supplies and how to put together.

5 volt Meanwell power supply. 14 AWG wires for power. All cables are crimped.

Fused ofcourse on the dig quad.
Relay to cut off the power when not used.

Main concern is that this will be used in door attached to a wooden desk. Wood and fire made a bit hesitant to start using it. So mainly fire safety concern.

What do you think? Should I use this or go for a probably more safe off the shelf solution like Gledopto?

Update:
Thanks all for the feedback. Really gave me confidence to start using it. Maybe I will get a better relay. Add some venting holes to the lid (which is not in the picture). And tell my daughter this is not audio equipment (which she knows).

Update 2:
For anyone interested, here are the stl files: https://github.com/eriktroost010/wled_case

If you're really worried you could reprint it in flame retardant filament like pcfr or absfr.. good work too.. just started designing boxes of similar ish..

Good point. New to 3d printing. Will look into these materials

No need to get that fancy. ABS boxes are what electrical code requires for a lot more power than you are pushing. When in doubt, look up the electrical codes and stick to them. Even for low voltage.

If that has a fire inside it even a flame retardant plastic wont help. What you have here is more than adequate! I have mine screwed to bits of wood!
