T90 Torx Tool

I needed a T90 Torx tool to change the desiccant cartridge on a Smart Fortwo (451) EV battery.    It's a seldom used tool because the desiccant cartridge is replaced every two years.  The German made T90 Torx on McMaster is $100+ and I don't feel like buying a cheaper version made in an authoritarian country.    Hence the genesis of this T90 Torx Tool.

I searched for Torx specification and found ISO 10664 online.    Using the ISO 10664 dimensions, I drew the T90 Torx outline using LibreCAD, then modeled it using OpenSCAD. Both the LibreCAD and OpenSCAD file are included for users to modify and generate their own Torx tools models using OpenSCAD, if needed. 

Anyway, over the years I've benefited greatly from the open source community, and must also thank Prusa for giving us the option of buying 3d printers made in a democratic country.
