OK, here you go -
Below are two links to native edrawings files that provide 3D models for the gross outlines of TextBlade, in the stowed and deployed states respectively.
Note that all the sculpts and detailed features are removed from these simplified blanks, but they do provide accurate overall scale.
edrawings has built-in measuring tools so you can query any dimensions you need to check compatibility with something you are planning.
Love that folks are experimenting, and can imagine some rough 3D prints for folks who want to get a feel for the stowed blade stack size. (It's really small!)
With the detailed surface and edge relief, it's actually even smaller.
Had to set up the Amazon assets so couldn't post it Sunday.
