What do you get when you combine a rocket, a test tube and 3D printing? Possibly the geekiest vase on the internet to beautify your home.
The *rocket test tube holder 25mm by MrNib accepts a standard 25 mm (0.98 inch) diameter test tube to make a nice space age bud vase that you can give to your favorite rocketman, rocketwoman, or friend from another planet.
A segmented friction ring near the top of the holder keeps the test tube from being loose when inserted. There is enough springiness in the design to handle slightly oversized test tubes.
Test tubes are not included but you can purchase them from supply stores like American Science & Surplus.
