The Straw Thermocouple Fastener (STF) was developed to secure thermocouples inside 0.25- and 0.5-mL French straws for precise temperature monitoring. 

The STF can be printed using both FFF or SLA, but has proven to be significantly more durable with resin.

Developed by the Aquatic Germplasm and Genetic Resources Center (AGGRC) at the Louisiana State University Agricultural Center. The STF was designed by Brittany Ratliff and colleagues, in partnership with the International Zebrafish Resource Center (ZIRC) and USDA National Animal Germplasm Program (NAGP). This work was funded in part by NIH Office of Research Infrastructure Program (ORIP). This device is part of a multi-year project to develop a series of open hardware to support development of standardized and reproducible tools for the research communities that use aquatic models to study human diseases.
