The PCB's arrived this morning and I have assembled both boards and tried fitting them in the housing, need to make some changes so I am working on another version. This was my first time using a stencil and solder paste. I definitely want to make a pickup tool and paste dispenser in the future, almost all the joints on the dimmer PCB had too much solder.

Assembly went fine, you can see more images on my Instagram: @lectro_net but here are some brief ones.
