All the STL Files for and Inverted motor mount belt driven Wades Extruder with part cooling duct and IR sensor Mount. 30mm spacing on M3 mount bolt holes to X carrier. J Head mount for Hot End. I designed this extruder because my original wades extruder had interference issues with the frame on my Prusa Steel and that limited my Z height to around 120mm on that machine. I wanted more and my machine was capable of more, so I inverted the motor mount to get it out of the way of the frame and the filament path and gave it belt drive to smooth it out and increase precision. I have made my very best FDM prints using this extruder.
This extruder prints smooth, quiet and extremely precise due to no backlash in the belt drive. The filament path is very short and that reduces the amount of "spring effect" you are going to get out of your filament path. 3 to 1 ratio on the pulleys, which more or less equals the same ratio as the very best direct drive extruders out there. You will need a 20 tooth pulley for the stepper motor and a 150 tooth G2 belt. You will also need some misc M3 screws and nuts. Installing and removing the J head is easy to do and is as simple as slotting everything together. The triangle on the clamp should be mounted pointing up. If you have an old Mendel or old Prusa that you want to fire up again, this would be a great way to do it and get the most out of your printer. I suggest having the part cooling duct printed on a resin printer if you can as it makes a superior part with better airflow.
