SkirtFlow M8P – 4x3010 Side Intake Stepper Driver Cooling Duct for BTT Manta M8P

SkirtFlow M8P – 4x3010 Side Intake Stepper Driver Cooling Duct for BTT Manta M8P

SkirtFlow M8P is a side-intake cooling solution for the BTT Manta M8P designed to pull cleaner air from the printer skirts rather than recirculating warmer air from beneath the electronics bay.

Unlike traditional bottom-facing electronics shrouds, SkirtFlow uses side-intake geometry to improve airflow quality by drawing cleaner ambient air from skirt openings while maintaining serviceability and multiple hardware mounting options.

Features

• Side-intake airflow design

• Supports 4x 3010 axial fans

• Cleaner intake path from skirt openings

• Improved directed airflow across stepper drivers

• Removable friction-fit fan mounting

• Multiple base hardware variants

• STEP + full assembly + Fusion F3D files included

Installation

1. Print selected Base version

2. Print corresponding Cooling Duct version

3. Install BTT Manta M8P to Base

4. Mount Cooling Duct to Base

5. Apply 1mm sealing tape to fan frame (2 sides is typically sufficient)

6. Install 4x 3010 fans

7. Wire fans as desired (zip-tie cutouts provided for cable management)

Included Files

• STL files

• STEP files for all Base variants

• Cooling Duct STEP

• Full Assembly STEP

• Fusion 360 F3D source

Design Notes

Traditional underside electronics fan shrouds often pull air from beneath the printer, where airflow may be warmer or partially restricted depending on table clearance.

SkirtFlow M8P uses side-intake geometry to:

• Pull cleaner ambient air from skirt openings

• Reduce hot air recirculation

• Improve direct driver heatsink cooling potential
