Bunk bed/cabin bed cup holder

thingiverse

My little one sleeps in a cabin bed and sometimes he gets up for a drink and wakes me, so I came up with this cup holder. This is version three, version two had his name on the bottom, and version one was a thinner, weaker prototype. The hook measures 20mm, and the top ring is 95mm; you can scale it up or down depending on the size of the bed and cup. I added a 15mm hook option. Version two is slightly smaller with a 70mm ring and 15mm hook.
