| Capton | 5 cm x 5 cm | Mouser | 25,07€ for 32m or 2,5€ |
Add re-use material for modules and textiles part. I found mine here 10€/1kg of fabric. And the PLA which I find in the LAB for the structure of some module part like little skins could be replace by bioplastic for the future I will add the files for the mold.
