Description
It is FAN holder for better heat distribution on drybox.
There are two wariants. One version with step-down cirquit and second without. It allow to use 12V 4010 fan on 24V power supply. I am using 12V SUNON MagLev ME40101V1-000U-A99 fan powered on 9V to reduce noise and LM2596 DC-DC Step Down Buck Converter Module
For FAN holder you need 2pcs M3x6 screw, plus M3x5x5 brass insert (I recomend this high quality ones). It is possible to use 4 screws, but I recomend use only two (on top or on back)
StepDown screws are M2x4 + M2x3.2x3.0 brass insert
Holder for Mini LCD Digital Thermometer Hygrometer need M2x6 screw + M2x4.0x5.0 brass insert
OpenSCAD sources are included.
