Wall-mounted filament spool holder

Wall-mounted filament holder. Allows better, smoother and more secure guiding of 3d printer filament. Holder made to not transmit vibrations from the roll directly to the printer. Provides better rolling (even for filaments weighing more than 1kg) and better printing accuracy. For the holder you will need three 22mm diameter bearings with an 8mm center hole (I used mine from a fidget spinner).
