Prusa i3 MK2 Top Filament Mount

thingiverse

I designed this mounting system specifically for effortless filament changes on the Prusa i3 MK2. The clever design allows the filament to unwind freely with virtually no resistance, thereby reducing the pressure exerted on the x-motor. This results in significantly less force being applied to the filament roll. To implement this design, I use a 5mm all-thread and my universal filament spool, which can be found at http://www.thingiverse.com/thing:2303240. Overall, this mounting system enables me to remove the spool with ease and produces prints with substantially fewer errors. If you have any questions or concerns, feel free to ask. I'm more than happy to provide clarification on any aspect of this design.
