I made this one to fit 2 coffee thermos mugs from Klean Kanteen for the center console of the Skoda Karoq, it fits, maybe not perfectly but it works for my needs. Printed it in Prusament PETG. with 35% infill, the wall between the mugs are fairly thin so add some more infill (not sure it is needed but it was very sturdy.
