An add-on for Monkeyfab Prime3D printer designed to improve cooling of extruded material. Unfortunately, during my test it didn't show any remarkable effect on printed things. However, If you own the same printer - you can try it yourself. If you found it useful, please let me know :) Compatible with Budaschnozzle hotend.
