I needed a way to store resistors for my electronics work.

Goals:

• Space for 75+ different resistor values
• Space for 375+ total resistors
• Quick and easy access
• Out of the way
• Cool looking

In researching a solution I found some folks who used test tubes. I loved the idea, but 75+ test tubes would take a lot of desk space.

So I decided I would design a custom rack solution to mount on the wall.

Parts:

• Test Tubes: Corning Pyrex Vista Borosilicate Glass Cylindrical Test Tubes, 3ml Capacity, 10mm diameter 70800-10
• Rubber O-Rings: Oil-Resistant Burna-N, 2.4mm wide, 9.6mm internal diameter
• Rack: Custom designed with Inkscape (TestTubeRack.svg) and laser cut by ponoko.com out of 3-Ply Bamboo Blonde (P3 Size)

Final Results
