2020 Spool Holder Horizontal Position

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2830534.

Just remixed it to shorten the overall length and place the screw holes on top and bottom. Also evened out the bottom to lay flat on the printer bed.

EDIT*** I just uploaded a new version after printing and the 2020 mount broke at the top. I beefed up the back of the mount area to hopefully keep it stronger.
