STL Files (which can contain authorship, copyright information and protected designs) are vulnerable for Cyber Physical Attacks as well as any critical process breaches. This could lead to theft of designs and IP. The costs for setting up highly secured file sharing portals are high. Even though the costs of these portals are high, they are still vulnerable for attacks because of the centralized character.
Topshelf offers an user-friendly file sharing system with the ability to securely send STL Files with the use of decentralized servers. Users will have a valid method to track the authencity of the file and data through the blockchain with the ability of verifying if an outside source has modified or corrupted the data.
