Ultimaker 2 Dual Filament Roll Holder

thingiverse

I added a second etrusion path to my Ultimaker 2+ and so needed a roll holder what would take 2 rolls. The longer roll holder Ulitmaker sells has in line and really won't work as there isn't enough room, so I designed this in Sketchup, printed it and it's now on my dual extrusion UM2+. This holder fits into the holes made for the regular roll holder. Along with this there is a cylinder that is a roll holder and a grip ring to hold the roll holder in place as well as the filament rolls. There is a screw that goes through the collar to tighten it. You can use a screw and nut or use the heat inserts from McMaster Carr that i used.
