Prusa I3 Biohazard filament holder

thingiverse

Easy to operate, a basic filament holder simply requires holding a standard role of filament with a center hole measuring between 40 and 105mm in diameter. To set up, position the end with the thread into the center of the holder and screw on the other side. This design functions without bearings, utilizing a M8 threaded rod to secure the center hole. The device rests atop two brackets positioned at the top of the printer, crafted by eddster. Note that the filament's thread is left-handed due to the design of my own printer; however, to accommodate right-handed threads, both models can be flipped accordingly. Although this model still needs to be printed out as it is a revised version based on an earlier design not yet uploaded.
