If you only use UP's original spools, UPPLUS spool small.stl will suffice. The big version just features a longer arm and as a result may require smart placement to be printed with an UP PLUS 2.
Before printing, I recommend you rotate and lay the 3D model flat or sideways (see the two attached pics).

###INFO:
The white spool holder in attached pics came installed with my machine, it was about 11.2cm tall and straight.

But my plastics gets snapped off after a while of not using it at a weird angle.

As a result, I have only print-tested 1) UPPL
