About this model

I have designed a better spool holder for my Original Prusa i3 MK2 that can fit any spools of filament and that makes the process of changing spools very easy! It is very strong and it can hold praticly every spool holder. I've done a lot of stress analysis with this design and with a spool of 2 Kg (twice the normal one) it has a safety factor of 11.38, so I'm sure it can take any spool of filament you like
