Dyson fan light blocker

Semicircular shield that slides around a Dyson bladeless fan to block the light coming from the display so you can sleep with it on your nightstand. Rotates back and forth to expose the controls or hide them. Original fits an AM09 heater-fan, new version fits an HP01 filter-heater-fan. Probably easy to modify in FreeCad (or just scale) to fit other Dyson products. Print with more perimeters and in a darker colored filament for more effective light blocking
