Ft5 r2 Stepper Driver Cooling duct with flow distribution

thingiverse

We overhauled this design to perfectly accommodate large heatsink stepper drivers. It's now more focused on the base of the heatsink for improved cooling performance. We achieved significantly better printing quality and drastically reduced skipping at high speeds (tested at 100mm/s). This model can be printed in PLA since the fan is always running. No supports are needed; a good cooling part fan is all that's required.
