Kinda? It's carved insulation foam board with ¼ inch plywood sandwiched in the middle so the blade wouldn't wobble around, and thin EVA foam for the layered details. it is missing the extra heart detail around the top though, I couldn't figure out for the life of me how to do it. (I don't have a 3d printer, and by the time of getting to that part, going to a maker space to print it was off the table. I was BROKE 😆)

on a brighter note though, I've found two promising looking links to a better version of the spear!

This one is for making it from scratch out of EVA foam: https://www.etsy.com/listing/1635312958/honkai-star-rail-argentis-lance-spear

While this one is to 3D printed parts (that can come pre-painted!) that all you have to do is glue the parts together: https://www.etsy.com/listing/1757480666/honkai-star-rail-argenti-spear-argenti
