No-rattle sheet holder - Core One

Holder is intended for a single sheet, but additional sheets could be accommodated with diminished anti-rattle power.

The design includes 7 recesses for 15x3 neodymium magnets.  The two sheet-retention magnets could be secured with hot-melt glue or wadded-up paper..

Sheet(s) are intended to be stored upside down (i.e., notched edge down) to allow tactile centering of the sheet in the printer recess.  However, sheets can be carefully inserted in the opposite orientation to satisfy users who want to read the sheet lettering.
