My interpretation of a weapon made famous by a game that sounds like Random Farts. Dubbed the Bladekey, this one has been designed to be printed at nearly a full metre length.

You will need an internal rod or tube to provide strength and rigidity for the print; it needs to be about 900mm long, and 20mm outer diameter.

Printing the chain and emblem may be tricky, so I have provided two variants - one with the emblem, and one without. If all else fails, you could always get some plastic chain and attach it that way.
