I wanted to customize the casing for my hackpad a little more so I applied a weight saving feature script onto the case on Onshape. I shaped the rib lines to give it a lattice like structure, and made sure there was still room for the screws. I also worked on the firmware part of the hackpad, just coding it to copy, paste, and undo as it was all i could think of right now. I’ll probably change this later on.
