Large toothbrush holder that fits most electric toothbrushes. i printed in .2 and 20% infill, but it really doesn't matter. There are two holes that you can put a nail or screw in but I used one and it works fine. I recommend printing this with the back facing down but it works sideways too. I designed this in Fusion 360 and it takes about two and a half hours to print at .2 and 50mm/s with 20% infill.
