TDI³
Welcome to my Tech Design Ideas Inventions and Innovations - TDI³.
You can download the STL files for free and 3D-print them yourself, please consider to support me.
If you safe money not to mention earn money with my ideas, It would be nice to get a donation.
My Designs are made with openSCAD - therefor i created a library you can use too.
Vale quam optime!
you may need 7zip to incompress the STL files, - which is also free.
