PWM Motor Speed Regulator Controller LED Dimmer box case

thingiverse

Compact case for aliexpress pwm controller ( https://a.aliexpress.com/_9A8Ck9 ) with soldered off connectors (permanent installation) The case features snap on cover, nice pcb fit with mandatory cutouts for the knob, in/out wires and status led (if printed with non-translucent filament). It's meant to be glued to something with double sided adhesive tape or with nylon ties through bottom slots (as on pictures). The controller is pretty good, features full-off mode with tactile click. The led is pretty bright, but should not be a problem when in case. For the fan I installed it on, the adjustment range is not very wide, as motor stops spinning when severe undervolted or may not start when turned on with lower settings (no full speed when on from off feature).
