Looking good intake ring for 4010 fan blower.
It improves air flow, and noise by 3-5% eliminating front leakage.
It uses just 1 gramm of plasic and 3 min. to print.
Designed to print with ABS, 0.4mm nozzle.
PLA was tested by "PetrosSystems" with press fit result.
For safety reason I'd recommend to fix it with small 2 drops of glue, or solvent.
