download for free on CGTrader, in case you want to skip my rambling and get something cool to print.
First of all, why am I modeling a knight? Well, besides getting to practice posing a model with the skills I learned from the barbarian, I'm working on a trophy for the YouTube web series TableTop. The logo for TableTop has a pawn, a D20, and a mini suitable for RPG gaming. So I figured I could offer just the knight and maybe start a whole series of generic 3D printable minis in my own style.
Why CGTrader? I want to support sites other than Thingiverse and since I first checked out CGTrader they've taken significant steps towards being a more 3D Printer friendly repository. And they have an option to sell models. So maybe I'll try them out for a while. If they have the options that Ponoko doesn't, CGTrader may be my new favorite.
