I have both the 2.4" screen versions for the sets that Helder is selling, as well as 2.2" versions if you happened to get ahold of the 2.2" screen I was using early on and are happy with that size.
Colors available are Peppermint (red), Spearmint (green), Cinnamon (maroon), Wintergreen (teal), Liquorice (black), and clear: (the image below shows an older version of the models, which didn't have the logo yet)
Price is $30 + shipping. I looked at services like Shapeways, and they were asking for upwards of $40 for the whole set, so that price wasn't pulled from thin air. :) These take several prints from multiple types of filament, so they take quite a bit of effort to put together!
