This is about 100.00, it is so much better to download kisslicer it is free and it works. also even if you use this and the 3d system, it still calculates how much filament you are using, and once the cube thinks it is out of filament, even if you are using bulk it will not print anymore. kisslicer is the way to go no more counting grams used......use all the bulk filament you want. This is just my opinion. thanks
