Ender 3 Pro Power supply case with 2xLM2596 step-down modules
thingiverse
This is remix of https://www.thingiverse.com/thing:4195582 Changes compared of original design: Cover: - I added one more screw and made the material around thread even more substantial - Removed mount for relay, moved one mount for LM2596 step-down module and added another one - Added labels for step-down modules (12V and 5V) Lid: - Added a wall to separate the lid (created space only for air circulation) and made it even more solid - Added a rib for extra solidity - Added bigger ventilation holes on the upper part, these holes are in a separate space and connected to the original ventilation holes of PSU. I highly recommend cutting ventilation holes on metal sheet of PSU for better airflow. See my photos for details. Assembly: - Use original screws to mount PSU and power socket to cover - Use M3 screws to mount lid (I used standard M3 PC screws)
