sorry for not providing different versions as the original model, but i have very little time
The author remixed this model.
i have a problem with temperature so i tried to reinforce the model, obviously this time it's heavier. still i tried to keep the filament path visible for easier inspections.
also i changed the screw keeping the lever arm as now every screw is inserted on the front, there is no need to take the motor off for disassembling the extruder.
