Filament Cooler for Geeetech i3 Pro B by Dr.One

thingiverse

I decided to create my own modified filament cooling system while printing because changing nozzles often meant dealing with varying lengths. My cooler is designed to be extendable, allowing the nozzle to be raised or lowered according to its height by simply sliding it up or down. This is an initial testing version, so please bear in mind that some imperfections may exist. A short print was made at a fast speed of 150mm, with 50% fill and 80% filament usage.
