NOTE: Development on Thingiverse has stopped. I will be continuing my development on Youmagine. https://www.youmagine.com/designs/parameterized-cup-holder The reason i am stopping development is Makerbot (the owner of thingiverse) has begun applying for patents for works done by the opensource printing community. This is theft of intellectual properties. I will leave this file up, but all future developments will be done elsewhere. This cup holder is designed to work with Love-Sactional couches, but would work with many other couches. you can scale this to fit any cup or couch arm.
