This im my design of a cup holder for a Mazda Mx5 NA. I once saw a similar design in a Youtube video but the guy didn't make his design public. So I made my own. It comes with custom support beam on the part that is screwed in. It is mounted on the side of the middle console with the screw that is already there. You should use ABS as filament so it doesnt melt in the sun. V2 of Cup Holder added, is a lot smoother.
