FlashForge Finder Bushing

This is a bushing for the flashforge finder onboard filament roll, so you can use AMZ3D 1kg filament roll onboard intead of using a desktop deroller. all you have to do is to trim the 1kg roll to180mm or less. Im using a Olfa precision blade, two pass with your knife then snap the plastic lid. No need to cut all the way trough. You need to remove the center piece of the new filament roll too!!! Sorry for my average english.....
