It's my first project modeled on FreeCAD and my first attempt with 0.18, it´s beautiful to have the complete project with plans and stuff in one single file

The Prototype is a Steel Prefabricated Clean Burning Cookstove based on the Rocket Stove Larry Winarsky Principles + Traditional Clay Stove Convection Principles and Technology from Mexico and CentroAmerica with some Ergonomic and Cultural adaptations for Mexican Food Cooking.
It purpose is to Reduce Indoor CO2 Emissions and Economize Wood Burning since we have so many places without LP GAS or Electric Stoves for Cooking and Boiling Water. The Steel Pan is designed for Tortillas, Meat, and Heating, the small Cap is for direct fire for Boiling Water, Sauces and Peppers.
Also you can Check the GITHUB Repository for FreeCAD files and Improvements. Its completely made from steel (Carbon, Galvanazide and Inox) and designed for small steel workshops.
