Tray for 18 glass tubes

A tray for 18 test tubes, usually made of glass, with a diameter of 30mm each. The tray has a total depth of 30cm, so it fits into my kitchen closet. It has a little edge grip to easily pull out of the closet.

Additionally a tube stand to get single tubes out of the closet such that it stands, e.g. on the table or the kitchen desk.

I use it as a spice organizer in my kitchen closet.

Good to be combined with this TrueFruits bottle tray for larger amounts: https://www.printables.com/model/1367329

Printed with PLA, 0.4mm nozzle, 0.2mm layer height, 20% infill, no skirt/brim.
