Community Highlight : 3D Printed Crane Anemometer
He Drew everything on Onshape, a free online CAD drawing tool, exported on STL and sliced as usual in Cura.
The anemometer is composed of a rotor, arms and cups that rotate thanks to an axle on a couple of bearings.
The wind , over a certain threshold, will make the anemometer arms spin.
The anemometer is mounted on top of the crane, the highest point of the machinery, to avoid air currents and vortexes that normally generate near big structures and buildings.
To measure the wind Tobias uses a bike tachimeter in line with the main rotor shaft, so he can have a reading from an LCD, possibly even in the crane cockpit by extending the cable for a few meters.
This project is definitely helpful for the application it serves, as it solves a tangible problem that involves usability and safety.
In many industrial and heavy duty/building sectors we see the use of 3D printing in small accessories like this.
It’s great to see that even with small components a big impact can be made to improve safety and situation awareness.
