I have finally decided to enter the 3D printing bandwagon. Having room for more hardware have always been the main inhibiting factor for not having done it longer ago. But with a little tidying up of the available space the impossible eventually became a reality. At least that was my reasoning, and the selection of a small resin printer seemed like an interesting choice in that respect, at least in what concerns the space occupied by the device itself.

I would often play with these, and try to connect to DC supplies or audio outputs from other devices, but was always frustrated with the sound never being nearly as loud as that produced in the original device.
