Bedside Cup Holder

I made this cup holder for my daughter who likes to have a drink by her bed at night, but would frequently spill the drink. 

The opening for the cup is 80 mm in diameter and 80 mm deep. The bottom opening is 33 mm wide to fit over a 1 ¼ inch piece of wood. Prints without supports (33 mm bridging). 

I printed it with 0.24 mm layer height and it took about 12 hours.
