Prusa i3 MK3 Low Profile Spool Holder

thingiverse

*Warning if you downloaded before 2018-03-25 see below The standard Prusa i3 MK3 spool holder is almost totally vertical which makes it take up the most possible space in the height direction. I had a height restriction due to the shelf my printer was going to sit on, so I designed this as a way to make it fit. This holder is angled backward allowing the spool to sit 2" lower and just behind / below the top of the frame. See the thumbnail showing a comparison with the original Prusa MK3 spool holder STL and this low profile spool holder. I have printed this and installed on my MK3 successfully, so far have not had any issues printing parts and having the filament roll off of the spool. *Model before 2018-03-25 had a protrusion on the frame clip that would hit the extrusion head while printing very tall parts. See image attached. In the new model it has been reduced so that this will not happen.
