Cup/mug holder adapter for car

Bottom part (the one that fits in the car's cup holder): 

• Bottom radius 62mm
• Top radius 72mm
• Height 65mm (pretty sure it does not touch the bottom of the cup holder)

Top part (the one you put the mug/cup in):

• Bottom radius 82mm (the brim rests around the car's cup insert)
• Top radius 85mm
• Height 72mm
• Floor height 2mm

It does not fit snugly in the car's cup holder. It prevents the top from falling out or wobling.

Nor does the mug fit snugly in the adapter - its easy to take out and put it, but still holds it from falling or wobling.

Printed at 0.28 layer height in PETG (car gets hot). You need support for the brim of the top part.

Tinkercad here.

Tested in Renault Megane 2020 and Geely Geometry C cars.
