My ultrasonic cleaner and add-on basket

My ultrasonic cleaner came with a metal wire basket, but there was absolutely no way I'd trust cleaning any pen part in the thing vibrating away against metal for a cycle of any duration! I found this plastic basket in a local dollar store, and it fits just right. Perfect for fishing things out of the bath of cleaning solution, too; not even springs (as agitators in ink converters) and such would pass through the gaps.
