Wanted a case for business cards. Prints quickly on mk MK2s. Fusion 360. I suggest you slightly size the top up a hair so its a snugger fit. 85mmx55mm business card.
Added V2. Top fits better and snugs at the back nicely.
3d printer for over a decade. Advanced 2d and 3d design. Engineer.
I closed my thingiverse and prusaprinters accounts due to political censoring of designs whilst allowing violent content to continue.
