For booties, I made a back insert (using Nexzr for the layout style) and a higher quality version of the translated manual (the original has lots of compression artifacts). Some day I'll get that shit made and sold for cheap, and I'll post a pdf/iso for those that would rather make their own.
As for a template, I have one (used for Motteke Tamago) in autocad that could be used for other games easily enough.... easy for those that have access to autocad and know how to use it anyhow.
