Snikt is scanned in its entirety by a group or person by the name of Rougher. Their homepage is here:
http://rougher.netfirms.com/ though I don't believe it offers downloads or torrents. I'd recommend trying to find it on an anime or comic direct connect hub (honestly you'll probably have more luck with a comic book hub, since it's only tangentally related to anime).
On the off chance that you're not yet familiar with Direct Connect go here:

The scans aren't too bad, but still a scan can't rival the original in terms of quality (and with art this good, you really want the best quality!), so I'd really recommend just buying the whole collection, now that it's compiled into one book and avialable on Amazon. But do what you'd like.
Hope this helps.
