Makerspaces help creative people in the community create, and in the case of Redditor DeusJZ, their resources can help make costumes and prop construction less expensive. Since DeusJZ had access to tools like a laser cutter at the Makerspace library, they were able to limit their costs for a replica of Thor’s Mjölnir to about $10. DeusJZ says:
The total cost for all the materials that went into this build was about $10. The mallet is made from a piece of free scrap lumber, the dowel rod cost $5, the grip tape was another $5. Everything else was publicly available through the Makerspace at one of the libraries I work at.
You can see a couple pictures of the transformation below and see the full build gallery at Imgur.
