About this 3D model

I refuse your Master Spool and substitute my own. Here you have a so-called Master Spool for Refills of Das Filament ( dasfilament.de ) 100% AMS compatible. Das Filament offers a spool available to download but you will need more than 300 grams to print it. This is because the way both halves of the spool are attached to each other. I went for another approach to that and instead of designing and printing a ginormous thread, I just used 4 M3 threaded inserts and screws. The total weight of this spool including screws and inserts is aprox. 150 grams. Try it out!
