Car Cup Mug Adapter

I made this for my Prius but check your measurements it'll probably fit lots of other cupholders.Bottom to top outer: 66.8mm, 78.5mm, 104mm Inner: 97.2mm Stem: 79.2mm Cup depth: 62.6mm Total height: 149mmI wanted a stem as deep as possible and a mug handle opening. It might be a couple of mils too thick but I also wanted to be confident it was strong.
