Filament Holder for the 3D Printing Nerd's Design Contest. It was designed for 1"x2" Filament Shelves with the idea of disturbing the filements on the shelves as little as possible. Most Designs I had seen seemed amazing and structurely sound, however it seemed like in order to put the holder in place, you would have to remove the filement to put it on, then put the filament back.
My design hooks with a solid hook on the exterior of the rear board, and the front hook swings up to latch on to the front board. Gravity pulls the pin into a notch to lock it in place. While I haven't had the chance to test if it will work as my printer is currently waiting for parts, I am hoping that it is structurly sound.
This holder was designed in Fusion 360.
