I tried printing the original base for this twice, but my filament simply wasn't cooperating (eSun's a bit of a mixed bag, and I've never had good luck with black filament for some reason). I wound up printing it in the same Colorfabb filament as the wheels, but first I thought of a simple tweak to the base, making it the same diameter as the driver wheel (that's the one with the peg), which makes the grooves of the driven wheel stick out a little, making it the most hesitant hand-driven buzzsaw money can buy... hence it being a free download.
The original base was nice for a desk, but this is for those taking advantage of your open door policy to look at your stuff and tool around with it. That's not knocking those fine folks. In fact, making it easier to hold is part of the design decision.
Maybe I'll make an upper part so all you'll see is the grooves of the driven. I'd have to think of a way to keep the driver wheel accessible.
