Coffee cup couch adapter

thingiverse

I needed a safe cup holder for kids near me. The existing cupholders on my couch measure 83.5mm across by about 50mm deep, and this adapter fits well at 83mm across and 54mm tall. I measured all my coffee cups and found the widest one to be 107mm across, so I made a spot for the cup that is 108mm wide. The walls of the cup holder part are nice and tall at 56mm so smaller diameter cups get good protection too. The handle opening is 23mm wide (which also fits my biggest coffee cup), and the opening starts at 6mm above the base to account for cups with low handles. I've been using this for about a week now, and I feel very relaxed while drinking my coffee on the couch as kids run around nearby.
