Ender 3 120mm Power Supply Cover - NEW VERSION - Quiet mod!
byMandicReally
Practical Printing - REPRAP Edition!
This new Power Supply Cover allows for installing a 120mm Cooling fan in place of the stock 60mm one on an Ender 3. This makes the Power Supply whisper quiet compared to its stock setup. The cover integrates a mount for a LM2596 "Buck Converter" voltage step-down. It also allows setting & adjustment of the buck converter after install. (Parts list below.) Design files include a spacer to move the PSU and allow Fan to Z axis clearance, this is REQUIRED for insall.
CAUTION: Modifying a Power Supply can be dangerous due to stored voltage in capacitors / transformers. Take caution when installing!
Designed to fit the stock Cheng Liang, model: P360W24V Power Supply that came on base Ender 3 models.
REQUIRES Soldering to wire Buck Converter to the Fan.
Fan is intended to pull air OUT of the PSU, drawing air in from the PSU vents and the cover venting.
NEW UPDATED DESIGN! (02/24/2022): Added holes to access the Buck Converter with Voltmeter leads AFTER install. This makes the project much safer overall. Also added a second version with different holes for heat insert installation (for the fan & buck converter).

- ** PRINT PARAMETERS:**
- Recommend minumum of 4 Perimeters and 10% Infill.
- PETG filament recommended, PLA has worked for me in the past though.
- POST PROCESSING:
- Take care when removing part from print surface as the hex mesh can be delicate and the design has a LOT of surface area on the build plate.
