A simple, compact card holder. The two halves are held together by those very small rubber bands you find in the hair care isle. These give good tension for holding the cards in place while allowing enough expansion to insert a 13-card stack all at once instead of one card at a time.
(Optional) Sanding the inner surface
After printing you may want to sand the inner surface of the discs to avoid snagging or bending the edges of the cards.
(Alternative) Rubberize With Sugru
For an even better grip on the cards, apply a very thin layer of Sugru to the inner faces and edges of the discs.
- Hook four small rubber bands on one clip.
- Using a bent paper clip or a piece of string, pull the ends of the bands through both discs.
- Loop the bands onto the other clip and remove the string or paper clip
- To increase tension insert one or both spacers by lifting the clip and sliding the spacer into position. The clip should settle into the recess at the top of the spacer.
