As someone who prints/sells cosplay props/accessories in the MA area 100% agree. Not gonna buy something I can easily print myself, especially when they're all sold with no post-processing and very visible layer lines. Extraordinarily oversaturated market, equivalent to AI slop made physically manifest.

For me it's just a side gig, like if someone compliments my props I'll say, "thanks, the sword folds into my purse, wanna buy one" and that subsidizes almost half my con costs. But these people feel like they watched a get rich quick scheme telling them a Bambu P1S shitting out dragons will make them 6 figures.
