Modular Filament holder

thingiverse

Another Filament Roll Holder. The Filament Roller Holders are used to insert filament rolls through holes (32mm in diameter; adjust otherwise). Nipples need 8x22x7 ball bearings secured by M4 flat head screws and washers. You'll require two per roll. Based on the desired number of simultaneous roll usage, you will need twice the Filament Holder Side component, as well as at least n+1 additional Filament Holder Center pieces for each roll. For instance, if using two rolls, install two sides and one middle; when using three rolls, attach two sides and two middles. You can directly fasten these holders to the wall or to a mounted board; the latter option eases leveling operations. Keep minimal space between Filament Holder components to ensure stability. To load filament rolls, simply hang them onto their respective Filament Holder. I employed settings: three perimeter layers with 0.2mm layer height and 35% PLA infill density.
