Hey!
While lubricating the Z linear rail on the A1 Mini some time ago I discovered a serious problem. The oil eventually ended in the components parts due to its viscosity and also gravity.
While I know most of the lubricating oils are not electro conductive I really don't think having the motherboard soaked in lubricating oil is anything but a dangerous situation to be in.
Lubrication became frustrating for me so I started to design something that would fix my problem.
I remodeled the bottom part and attached a reservoir system to it and a little bit of sponge.
