e modèle est un capuchon imprimable en 3D pour tube à essai de 25 mm de diamètre, conçu pour accueillir une LED standard de 5 mm. Il est spécialement adapté aux expériences de biologie végétale, notamment l’étude de la croissance des plantes sous lumière (phototropisme, influence de la couleur ou de l’intensité lumineuse).La LED éclaire directement l’intérieur du tube, permettant d’observer les réactions des jeunes pousses ou de petits végétaux en environnement contrôlé. Le capuchon est démontable, réutilisable, et la LED est maintenue par friction, sans colle.Idéal pour :<ul><li>projets scolaires et scientifiques</li><li>expériences de SVT / biologie</li><li>démonstrations pédagogiques</li><li>makers et enseignants</li></ul>🌿 Tube Ø 25 mm 💡 LED Ø 5 mm 🧠 Biologie &amp; éducation 🖨️ Impression simple et fiable

This model is a 3D printed cap for a 25 mm diameter test tube, designed to accommodate a standard 5 mm LED. It is specifically adapted for plant biology experiments, particularly the study of plant growth under light (phototropism, influence of light color or intensity).The LED illuminates the inside of the tube directly, allowing observation of the reactions of young shoots or small plants in a controlled environment. The cap is removable, reusable, and the LED is held by friction, without glue.Ideal for:<ul><li>school and scientific projects</li><li>SVT / biology experiments</li><li>educational demonstrations</li><li>makers and teachers</li></ul>🌿 Tube Ø 25 mm 💡 LED Ø 5 mm 🧠 Biology &amp; education 🖨️ Simple and reliable printing
