Universal handguards

Reindeer Husbandry Applications require use of snowmobiles to get around in the tundra like conditions of Russia. Hand guards are often used in snowmobiling to protect the hands against wind, snow, and tree branches. However, these guards can be used in other instances as well. Such as dirt bikes, ATV's, and bicycles.
Problem[edit | edit source]
3D printing can help create products for areas where products are hard to ship, deliver, or manufacture. These hand guards are designed to be easily printable and easily replaceble if parts are broken in extreme circumstances.
Solution[edit | edit source]
A 3D printable set of handguards and mounts that can be adjusted or changed through the OS software to fit any custom needs.
These are currently designed to fit a 1" handlebars which are pretty common.
