Another Horizontal spool filament dispenser, this time designed to hold 3kg spools, with modifications the top side may hold other size spools as well. There ia a 175 mm throw for the feed arm for filament, meaning that any spool up to 350 mm (14 inches) with a 45 mm opening at the center, should feed through this feed system. The Filament may be fed through the slot, or the hole at the top of the feed arm. (the latter may help in some cases with preventing filament from spinning off the spool and getting caught under it. This also uses an LM11949 tapered bearing, not included, If there is a need I can remix for a 608 bearing, but I don't consider that a recommendation.
