I think i'll be making a mold of one of them next week, in order to experiment with resin :)
I don't plan on 3d printing them if i will produce a larger quantity, the 3d printer is simply too slow. It's great for prototyping though, and we have an awesome SLA printer (3d printer using liquid) at uni, which i would love to try out!
Seems like there is some interest behind it, which is definetely awesome!! Would love to share them with people!
