Makerbot Z18 Filament Spool Holder - Strut Type

thingiverse

This holder attaches securely to the rear corners of a Z18 (top cover removed). Once in place, it becomes rigid and functions as an integral part of your printer. This structure has been optimized for vertical loads and boasts a high fundamental frequency similar to that found on bridges. This means you can load up to 10 spools of filament onto it, even move your printer around without dislodging the filaments. By using these holders, you won't have to worry about weight or vibration affecting your print quality, and this also helps prevent costly filament jams. The design features a top slot for storing filaments that is precisely 6.5mm (1/4 inch) wide, allowing for easy insertion or removal of a metal bar up to 6mm thick. An aluminum T-profile is currently being utilized but you can customize the slot to accommodate any rack as long as it has sufficient strength to handle all the filaments you plan to store on it.
