Needed somewhere to place a pop/soda can while pushing the kid on the swing. Was designed around the size needed. Ended up using the same one to place in the kids crib when she was sick to throw her water bottle in as well. 

Fits standard 12oz cans/bottles. 

Printed in PLA, but depending on the sunlight where you place it. Might be better in ABS/ASA. I've had mine in the shade outdoors for ~1 year without any deformation.
