Designed a table tidy/caddy, napkin holder, or whatever this is called for the salt and pepper shakers I designed (https://www.thingiverse.com/thing:3063252).
Takes 6 of our relatively thick coasters (45mm space), a bunch of napkins, and two shakers (37mm diameter hole).
Printed with transparent PETG with circular infill for a nice effect.
Also printed two TPU feet and attached with super glue. They don't work quite as well as I'd hoped, but probably much better than it would have been without.
No supports/rafts/brims required.
To reduce its bulk, the dividers are only 5mm thick, but being 90mm tall, I'd suggest multiple perimeters and/or high infill.
