6.5.3 Other useful open-source biological research tools
There are many other useful open-source biological research tools already available and this
book does not even atempt to catalog all of them, but I would like to pique your interest in
using and sharing OSH, so consider the following simple examples of tools that can save your
biolaboratory money.
Racks for vials and test tubes proliferate on the open-source scientific hardware community.
For example, you can get test tube racks that are made with laser cuters 84 as designed by
Thingiverse user Eithen and shown in Figure 6.80 or with 3-D printers 85 as designed by Thingi-
