My nephew printed out some little ufos that have an alien inside. I was trying to find some tall domes that are around 13/16" diameter and around 5/8" tall. I don't think Plastruct has domes like that. Any idea where to look? I was thinking I might have to go find the little gumball machine things at the store because they had the right shape. I don't even know any stores that have those now though!
