Éolienne de type Savonius Modélisation paramétrique : * Modification de http://www.thingiverse.com/thing:366102, avec l'ajout d'une base avec une gorge pour la courroie: [[Fichier:Savonius.png|sans_cadre]] * Création d'un support d’éolienne + moteur, avec contraintes de réglage pour la courroie: [[Fichier:Micro eolienne bras.png|sans_cadre]] * Assemblage final : <gallery> Fichier:micro eolienne assamblage.png Fichier:Micro_Eolienne_scad01.gif|Gif animé Fichier:Micro_Eolienne_scad02.gif|Gif animé </gallery> * Code, un peu merdique : <syntaxhighlight lang="C"> Savonius_Diametre_Base=100;
