Quoted from NinJaBooT:
I'm not knocking TMezel's mods but I'm not a fan of 3D printing quite yet. The quality in comparison to injection molding or resin casts isn't quite there. As well if you compare Matt's to Mezel's you will see that Matt's looks much more like the one in the movie and his mod has been approved by WB. Just cause your the first out the gate doesn't mean anything if it isn't the superior product. Kudos for both of them but I think Matt created a better version.
Don't be embarassed. Evident differences between Matt's pro stuff and homebrew 3D printer stuff. The BAC city looks far bett err an more accurate imo. As does the tornado. heck, I prefer my clear-ish homemade tornado to the mezel one. But people will buy/install what they like. More options are good.
