4 inch Vent Damper
thingiverse
I needed a damper for my spray booth window vent but wanted a solution I could integrate with HomeAssistant. I didn't like what I found so made my own. I used a SG90 for a servo and NodeMCU via ESPHome. Also used 2 608 bearings and 2 M2 w/locknuts on the rod, and 4 M3 with heat set nuts attaching the servo cover to the body. I tried to upload the finished product but can't seem to lower the resolution <500kb.
