“Freedom is the right of all sentient beings.” - Optimus Prime
I recently rewatched the 2007 Transformers movie and I thought that Optimus' Energon sword arm that he used to absolutely brutalize Bonecrusher, and I just had to make it for my Dummy. You might have to jostle it a bit to get the sword to fit, I suggest putting the end into the hole on the frame, then laying it flat and lightly pushing. It shouldn't need that much effort, but the clearances are a bit tight. Hopefully it should just work on most printers, it worked fine several times on mine. I printed both the sword and the frame in PETG.
The middle of the frame is a relatively long bridge, you might need supports, but you should be fine. Just clip off any extra extrusions along the bottom and you're good to go.
Here's the full fight, just so you can understand why I NEEDED to do this lol
The author remixed this model.
Modified the original forearm frame to accept a sword.
