This is a full kit with the following:
1 - E3D Thermistor
Designed to have a small form factor, low mass, short retraction, and optimized heat transfer, the Mosquito uses the highest grade materials available, all engineered and built for performance here in the USA.
Mosquito is built to accommodate standard 6 mm heater cartridges, 3 mm thermistors, and RepRap style nozzles (The same as E3D). We also highly recommend the use of Capricorn XS tubing during installation to achieve the best printing results.
Designed & engineered in Gainesville, Florida; manufactured and assembled in Indiana.
