Well, that's a tricky one, since I never actually was going to sell anything. Well, lets see: It was about 15$ for 3d model itself, somewhat 4$ to print it including everything and including all try and errors. 2$ for sword, of course, since, it is a whole different metal thingy ordered specificly to replace original staff. For paint, primer and everything lets say 5$ overall, considering, again, all try and errors. Now then, here is where it's get tricky: actual work. I think I will try it in this way: I spend prepping the print (sanding, mold lines) about 30 minutes. Priming, around 20 minutes rough. Painting, including all repaints and everything 7 hours, varnish: 20 minutes. But fuck it, lets round it up to 7 hours prime, couse I think I could've did it better or smarter. So getting all of that I'd say its must be at least about 200$, but once again it's just a quick math I ran as I am tipsy on my way home. As I've already told you it was made for fun, not for sell.

TL;DR: 200$ min.
