PROTOTYPUM is a Czech design and innovation studio focused on industrial design, prototyping and engineering founded in 2015 in Prague.
Trezor is a hardware wallet for cryptocurrencies (so-called cold storage) but it can be also used for secondary authentification to your email or as a password manager.
PROTOTYPUM team worked on the project from the first sketch and continued through CAD modeling, prototyping by 3D printing, prototyping in silicone and finally, preparations for the final serial production. During the first stage of prototyping, a lot of 3D printed prototypes from the Fillamentum's Flexfill 92A has been printed (over a hundred pieces). This flexible material helped them to test the features on the design before prototyping it from silicone. Fillamentums's Flexfill 92A material actually helped them to develop the product much faster and also cheaper.
