Whoa, it has come to my attention that the download links with tinyupload.com expire automatically after some time of inactivity with those files, and also that hosting site itself sometimes goes down entirely, for reasons unknown.
Anyway, I have reuploaded all files to mediafire.com and updated the Downloads page of this blog. If the downloads become unavailable again, please let me know via the Shout Box at the sidebar of this blog.
Also, thanks for the suggestion for uploading to Thingiverse. It's a cool site, but I just wouldn't be motivated enough to provide all the step-by-step instructions expected there. All I provide in the download is the .pdo, which should tell you everything you need for building the papercraft model. You are expected to have some basic proficiency and experience at building papercraft models to implicitly figure out the optimal build order and such. If you run into some particular difficulties in building one of my models, it may be just because my designs are kinda awkward in some situations. I might discuss those situations here on my blog and how I dealt with them. I hope that helps!
