The Mosquito™ hotends are now updated and have a new coated heat break!

They bring superior heat break performance – conduct 85% less heat than a standard threaded heat break. They have increased structural rigidity. Even more than before. They are rated up to 450°C temperature to cover a wide range of printable thermoplastics. Mosquito™ hotends are compatible with BMG-M, BMG-X2-M, QR-M, and LGX extruders from Bondtech.
