New Product! 3D Printed & Open-Source Propeller for the M100

We have a new product available today. It’s a propeller specially designed for the M100 Motor. There are lots of applications where you don’t want or need a full blown thruster, like on small ROVs or surface vessels. Together with our OpenROV Mounting Hardware, this propeller could be used for the forward thrusters on the OpenROV.

The propeller has a 68mm diameter and generates about 3.2 lb of forward thrust and 2.6 lb of reverse thrust. There are clockwise and counter-clockwise rotating versions. Thanks to the magic of 3D printing, we can build these in small batches without the need for expensive injection molded tooling. We are selling the propellers here for your convenience, but many of you have your own 3D printers and can print the propellers yourself. We are making the 3D files for the propeller open-source and licensed under CC-NC-SA 4.0.

The 3D files are available here for free (and also on GrabCAD).

Here is a chart of the propeller’s performance on the M100 Motor. Note that our propellers are printed using the SLS method, but you might get slightly different results with other types of 3D printers.
