Twist in cable clamps for aluminium profiles (ITEM profile 8 compatible)

Remixed from (inspired by) https://www.thingiverse.com/thing:2613532 to fit ITEM Profile 8–compatible aluminum profiles. I’m really happy with these cable clamps — I’ve printed at least 50 of them and use them everywhere in our experiment. Very convenient. If there is a company that wants to commercialize these, please do so :) these could be a lot cheaper mass produced compared to printing them I think. I would buy them!
