I'd love to hear feedback on the force pike, aside from modeling and printing a piece to attach a couple pieces of corrugated hose to a fan to run to my bucket, this is really the only experience I've had with trying model something of my own.
I made this pike 1420mm long since I' rather tall (6'6"), but should be able to adjust the length for others. Not shown on this sheet is I have the model threaded an separated into 4 pieces, the pommel and the rest split into 3 pieces.
