Not exactly a base hugger, but there's nanoscreen bases already at Thingiverse: https://www.thingiverse.com/thing:2951973 I've printed some for Victor Messer and all the shasvastii who has one, they look nice.
I saw that one. I was hoping to find a base hugger. I put my nanoscreens and tinbots on metal tape which works with the magnetized bases. I want to reduce the number of tokens I need to manage. I don't mind so much for unconscious and immobile models. But having to move tokens on models that are in a link is a personal pet peeve.
