About this 3D model

This mod allows you to add 5015 fans to cool down the stepper motors and the electronics. It makes your printer live longer and avoids skipped steps due stepper motors overheating. Print with 0.2 layer height, 4 perimeters and 40% infill. No supports. PETG is ideal, but PLA will work too. Note: There are build-in supports in main part, easy to remove.
