Creality 32bit board case with Intel CPU cooling fan duct for Ender3 Pro, V2

thingiverse

A standalone Creality 32bit board case with duct for classic Intel CPU cooling fan. 1. I modified the case from Jakeleee and added duct of https://www.thingiverse.com/thing:4138132 2. This case is suitable for all Creality 32bit control boards used in Ender series to set out of printer enclosure to avoid overheat. V4.2.2 and V4.2.7 board passed test. 3. For Ender 3 series user, only Z-axis limit detect cable needs to be extended for set up out of printer enclosure. No extend cable needed if you use BLTouch, just remove Z-axis limit detect cable from control board. 4. All classic Intel CPU coolers can be attached without any modification but best fit with removing white 4 nails used for attaching PC mainboard. 5. A DC to DC down circuit board (eg. LM2596) required for Intel CPU cooler to 12V DC supply from dedicated 24V connector on 32bit control board. 6. Attaching rear panel is not recommendable for better cooling efficiency, or attach additional 40mm cooling fan on it but not actually necessary. One Intel fan is strong enough.
