Hi commenters. The description on the project page says:

"This rack was designed to be laser cut out of 3mm acrylic and to hold 20mm diameter test tubes (like these: http://amzn.to/1xqkpfI). I'll be using it as a spice rack."

The tubes in the current design are 20mm.

diameter of tubes please?

Looks nice! What size tubes did you use?
