The FlashForge Finder and Inventor II series are compatible with 1.75 mm PLA filament. If you happen to have PLA spools that don't fit inside the build-in filament casing, then this external spool holder makes it easy to fit them on your 3D printer.
The holder's axle is hollow to accommodate one or more units of the Universal Filament Filter and Lubricator. The end of the axle has a thread that fits the corresponding screw cap. We recommend using this small filter/lubricator to keep the filament clean before it enters the extruder.
Please note that when using this external holder, the filament bypasses the built-in filament detection switch. Therefore the printer won't be able to sense when the spool runs out of filament and pause the 3D-print. If you use external spools you will need to turn of the filament sensing feature under the settings menu on the machines touchscreen display.
Also included in this thing are pre-sliced ready-to-use .gx files you can copy to a USB stick and print directly on the 3D printer. Download the Pre_sliced_ready_touse.gx_files.zip which contains these files.
