I just finished assembly on the transforming papercraft of G1 Scrapper by PaperTang. His original templates called for colored cardstock and I only have white. So I imported his templates to Photoshop and colored, textured and weathered them. I asked PaperTang if I could offer the file on my site for download and he said no. So if you are interested in grabbing this papercraft shoot me a PM and I can send it to you. [edit]ends up the file is too big to email sorry![/edit] You can also signup as a member on my blog to be able to download it from there. Here's the blog post with download link and full gallery
The designer of this model also did a Mixmaster, but it doesn't look as quality as this one. While Scrapper can form a leg it doesn't look like Mixmaster can do the same... I fully agree though that a complete set of constucticons that transformed and combined would be really awesome.
