In our 3D printers, we use a plastic filament extruder. This is an extruder named Goliath (www.tytan3d.com). It is composed of : extruder, motor,board linker gear and drive gear Mk7.
It tends to get dirty quickly. This is an essential element of 3D printers. Its malfunction causes a poor quality of printed parts. It must be kept clean.

But maintenance is difficult. Why? :
•It takes at least 6 minutes to disassemble / reassemble the motor and to clean the parts making up the extruder.
•Access is often difficult.
•The passage of the filament in the extruder is sometimes complicated.
•Sometimes the filament breaks in the extruder. We must disassemble all to remove the filament pieces.

To remedy this, we developed the EasyFix, an adaptation part. It allows disassembly / reassembly in 15 seconds.
Maintenance, cleaning and access is greatly facilitated.
