The spool holders that come with the Flashforge Creator 5 are ony 66mm long, so they cannot fit normal 1kg spools from vendors such as Prusa and others. This model is a design compatible with the original mount an it's designed to be a dropin replacement. PM me if you need other dimensions as the model is parametric, so they're easy to make.

Model is made to be printeable without supports, but can benefit from adding a litte (but only on bed, not internally). Has room for a M4 screw if you need some extra strength. Grid pattern reduces filament usage. Modeled in Fusion360. Printing with PLA as supports on FFC5 works great.
