Spool holder for DaVinci Pro

This is a spool holder for use with an XYZ Printing DaVinci Pro. My dad designed it as a replacement for the plastic cover that goes in the printer's handle. It snaps in place on the left hand side.

I moved the printer to a space where more space is available on the sides than at the back, making a spool holder like this useful. I prefer this to other hook type designs, as it keeps the side closed and cool drafts out of the printer.
