Hinged Side Mount Spool Holder

Simple, Clean, Side Mount Spool Holder.  I tried to design this while keeping in mind maintaining the uncluttered appearance of the PS1 and X1-C.  Im also anal about avoiding using supports and at the same time keeping in mind strength and as low as possible print times.  That being said only one portion of the hinge part 1 uses a very simple support that snaps out easily.  The roller itself has a plug that pops in to form one of the spindle ends thus allowing for the roller to be printed in the vertical orientation for a smooth finish where in matters.  I had printed this for my own use about 4 months ago but delayed posting it until I had it installed with a full 1kg spool hanging off of it to insure it would not sag even printed in simple PLA or PLA+.  The mount works just as well with or without the Roller Option.  Please note that when the Spool holder is folded down its still at a slight angle to insure the spool stays tucked in close to the side of the printer and is centered with the filament guide included on the second print plate.
