I needed a take away coffee cup holder for my baby carriage. I did not find what i want, so i designed one.-infill 30%, no diaphragm -no support (it can be printed with support, but removing it will be difficult, especially from the square holes) -use a pen knife to clear holes for glueing back mounts -the upper hole is designed to fit the biggest cup i found in my whereabouts -use knife to cut the length of back mounts in order to fit your carriage
