Propeller - 4 Blade 41mm

41mm diameter propeller designed for my new 1/20 scale tugboat. This is designed to accept a 3mm diameter shaft, with nut. I have not tested this one yet, so no feedback on actual use. Designed to be printer with no support, it can be done with either a brim or raft for adhesion purposes. You might need to sand / file a bit on the edges.
