These risers allow the entire Creality Ender3 V2 printer to be raised by approximately 18mm, allowing better air circulation underneath the printer, thus increasing the quality of cooling. The system is compatible with both standard cooling and custom covers for larger fans. Two STL models are supplied, one designed to be fixed with screws and one free to be moved.
