Bunk bed/cabin bed cup holder

thingiverse

my little boy sleeps sin a cabin bed and comes into me for a drink some nights and wakes me,so i put together this cup holder and he loves it. this is V3,V2 has his name in the bottom and V1 was a thinner weaker version. The hook is 20mm and top ring of 95mm,you can scale up or down depending on size of bed and cup. Ive added a 15mm hook version V2 is slightly smaller with 70mm ring and 15mm hook
