A little case designed for this TPA3116 amplifier board.
There are many versions, I have the one pictured and this fits like a glove. I've uploaded the step file for easy tweaks if your board is a little different.
Looks nice with the sides printed in a different colour to the body.
It's friction fitted and doesn't move a mm in my own print. Some hole compensation may be required if your printer tends to shrink holes a little, though I have added some tolerance already.
The author marked this model as their own original creation.
