Summary

Paper napkin holder for 6" x 6" napkins.

Instructions

Paper napkin holder for 40 to 50, standard six-inch square paper napkins.

The basic design sits on the table.

I also made one that hangs on the wall. I haven't tested it. The tab doesn't look strong enough to survive for long, but I'll update this project if there is a need.

That wall mount file includes a tall, thin "sacrificial" bar so the extruder doesn't hover over the that upper tab, melt and distort it.
The bar gives the small upper section a little time to cool between layers, as the extruder moves back and forth between them.
Fan cooling might be another option.

The STLs appear to have some weird vertical lines at the edge of the diamond shapes, but I couldn't find any defects and they printed without error.

Plan on 3 hours, 77 grams ABS, 0.3mm layers, medium speed with an Afinia printer.

A Metric version of the table-style is included.
BTW.... Scaling up by a factor of 25.4 will scale any SAE (inches) file up to the metric equivalent to suit printers that require metric dimensions.
