Test Tube Rack

thingiverse

This rack was engineered to be laser cut from 3mm acrylic and crafted to hold 20mm diameter test tubes like these: http://amzn.to/1xqkpfI. I will utilize it as a spice holder. Instructions Cut out three tube cradles and the two side frames. Take note that the bottom tube frame should have the circle engraved instead of cut (this allows the tubes some roughness to sit on and prevents slippage). Next, assemble everything and glue together properly.
