PCR Tube Opener (0.2 mL tube), Various Sizes

Very easy-to-print PCR tube (0.2 mL tube) opener, designed to be able to open 3 or 6 tubes at once. Also makes it easy to close them. There's clearance to access the tubes if you skip a row in a standard 96 slot PCR tube holder. 

If you've ever done PCR, you know how tedious it is to be opening each tube by hand. This helps accelerate that process.

I also made a 9 and 12 tube-sized opener, but have not tested them. 3 and 6 were enough for my needs.
