DeepCool CH270 Riser Bottom Stand Improves Airflow, High Aesthetic Appeal, Includes DC Logo, Vertical Airflow

With this riser stand, upgrade your CH270's vertical airflow. Not only will cooling be "calmer," but your desktop's aesthetic appeal will also improve. Happy Printing & Stay Cool!

A complete introduction to the 3D printable "riser / bottom stand" model for the DeepCool CH270 chassis, ready for direct printing. Modification and commercial re-modification are prohibited without permission. The model has been tested in multiple vertical airflow configurations and significantly improves bottom intake efficiency. It also features a DC (DeepCool) logo decorative surface, balancing performance and aesthetics.

I. Design Highlights

1. Custom-made for CH270
   • The model dimensions in the 3mf file match the CH270 bottom dimensions, requiring no additional modifications.
   • Raises by 50 mm, providing space for power cables, USB-C cables, etc., to pass through, preventing excessive bending that could lead to poor contact.
2. Airflow Optimization
   • Four-sided through grille + 45° diversion bevel, increasing intake area by ≈38%, creating a more stable positive pressure vertical airflow.
   • The bottom space can accommodate 2×120 mm reverse-blade fans, or it can be used directly as a passive riser.
3. High Aesthetic Appeal
   • Integrated recessed DC (DeepCool) logo engraving on the front, which presents a metallic texture when printed with PLA Silk.
4. Easy-to-Print Structure
   • Enable automatic tree supports, and it can be formed in one go with 0.2 mm layer height / 0.4 mm nozzle.
   • Split printing option: can be disassembled into 4 parts to reduce warping and is compatible with 256*256 mm small-sized printers.
