## Measure models
Open web app [at](https://0x00019913.github.io/meshy/) and import it to get the volume.
Volume is 21037 mm3.
To convert 21037 cubic millimeters (mm³) to deciliters (dl), you can use the conversion factor that 1 deciliter equals 100000 cubic millimeters.
Therefore, 21037 cubic millimeters is equivalent to 0.21dl.
## Required Material
- Durcisseur : Correspondant à la résine choisie.
- Fibre de verre :
Tissus de fibre de verre : Différents grammages, comme le roving (tissé) pour la solidité et le mat pour l'imprégnation.
- Fibre de carbone :
Tissus de fibre de carbone : Pour des pièces plus légères et très résistantes.
- Résine époxy : Choisissez selon les propriétés mécaniques et la température de travail. Il est préférable d'utiliser une résine époxy de bonne qualité pour des pièces finies robustes.
## Required Tools
- Gants et masques : Pour la sécurité, car les résines époxy sont toxiques.
- Scellants et cires de démoulage : Pour faciliter le démoulage et éviter que les pièces ne collent au moule.
- Ciseaux ou coupe-couteau : Pour découper les tissus de fibre.
- Pinceaux ou rouleaux : Pour appliquer la résine.
- Système de dégazage : Optionnel, pour éliminer les bulles d'air dans la résine, améliorant la qualité du composite.
- Seringue
