Having a screw loose

On the top you can see the Raspberry Pi that controls everything. Underneath is the printer battery holder and the Raspberry Pi HQ camera module.

Every now and then at emf someone would ask me if the nut, bolt or washer they’d found on the floor was from the Custard Cream Camera. It usually was. I’d got everything nice and tight when I built the camera, but the jostling must have worked things loose. Also, I think that PLA (the filament type that I used) tends to deform when compressed, which loosened things. I’m going to have to add some locking nuts and maybe some varnish to hold the parts of the case together.
