grabcad

This micro test tube has a 1.5 mL capacity and features an outer diameter of 9.6 mm. The cap's outer diameter is 12.6 mm, with a height of 8.813 mm. With the cap on, the overall height is 48.5 mm. A small line inside denotes the exact volume. The screws are proprietary, with specifications of 9.6 mm diameter, 2.5 mm pitch, and 3 revolutions, no taper, and a profile of .25 mm x .5 mm. For 3D printing, print the tube right-side up with minimal supports, while the cap should be printed upside-down with minimal to no support. The cost for printing in PLA is approximately $.05 per tube. While it's cheaper than buying 500 commercial micro test tubes, it may not be as cost-effective as buying 5000 from most companies. Please leave a comment if you have any suggestions for improvements, such as adjusting the O.D. size to fit centrifuges or tube racks. Enjoy!
