This is a custom cover for the W1209 module found on Aliexpress (https://www.aliexpress.com/item/W1209-Mini-Thermostat-Temperature-Controller-Incubation-Thermostat-Temperature-Control-Switch-Digital-Thermostat/32391033016.html?spm=2114.01010208.3.17.54Q25R&ws_ab_test=searchweb0_0,searchweb201602_4_10152_10065_10151_5010011_10068_10136_10137_10060_10138_10155_10062_437_10154_10056_10055_10054_10059_303_100031_10099_10103_10102_10096_10052_10053_10142_10107_10050_10051_5030012_10084_10083_10080_10082_10081_10177_10110_519_10111_10112_10113_10114_10182_10185_10078_10079_10073_10123_10189_142,searchweb201603_16,ppcSwitch_5&algo_expid=99360b00-0f44-4f83-82a0-ca48881e02a1-5&algo_pvid=99360b00-0f44-4f83-82a0-ca48881e02a1) or other online stores. The cover features holes in the bottom plate to securely attach it to a surface. I created two versions, one with all cables passing through a hole in the back and another that uses aviation type connectors. The version with aviation type connectors includes labels on the back and side above the connectors for the sensor, fan, and power. Spacers are used to achieve the correct position for the display and menu LEDs. To securely attach the module, four long M3 bolts with nuts are required. When mounting the bottom to the cover, tapping the holes with an M3 tap is necessary.
