Easy printable and great looking adapter plate to mount an ultimaker 2 plus feeder to an ultimaker original (plus).
In this solution you set the adapter plate between the plastic and metal part of the UM2+ feeder. Because of this you can print in PLA (ABS isn't necessary) and no additional parts (like screws or nuts) are needed.
I use it together with the feeder damper (https://www.thingiverse.com/thing:2723098). Both together worked really great.
