Heatermeter Rotary Fan/Damper

thingiverse

This is a custom design for a rotary damper/fan, tailored specifically for use with the Heatermeter project and inspired by Ralph Trimble's work, which can be viewed here at http://www.thingiverse.com/thing:1048999 . The system employs an affordable Suno 12V 50mm Blower (which may be compatible with other brands as well) and a Tower Pro MG90S servo. You can find the fan component here on http://www.digikey.com.au/product-detail/en/GB1205PKV1-8AY.GN/259-1317-ND/1021167 . UPDATE: A secondary option has been integrated into the design, offering an alternative top case and damper configuration featuring three holes instead of one, which effectively increases the intake's overall cross-sectional area. This change also reduces the extent to which the servo must move in order to transition from fully open to fully closed, though it remains uncertain whether this modification will affect the overall resolution of the system; an experimental approach is therefore recommended. It is also worth noting that you might need to remove one of the flanges from the servo to prevent it from protruding beyond the confines of one of the holes. Printer Specifications Printer: Flashforge Dreamer Rafts: No rafts are used. Supports: Yes, supports were employed. Resolution: 0.20 mm was used as the resolution.
