Video laryngoscope blades number 1, 2, 3 and 4

Proyecto ALBA is a collective of Mexicans, predominantly engineers, working together to share techniques, tools, and knowledge with medical teams fighting COVID-19 in Mexico. To expand their reach, they're sharing three low-budget videolaryngoscopes, designed using Finite Element Analysis to ensure safety. The estimated safety factor is 3.5 under a 20 kg load, while the blades are subjected to 17 kg of force in the middle, measured with a dynamometer, without showing any signs of bending or cracking noise. Several doctors have reviewed the models and agree that they meet the required stiffness for use with patients in areas lacking videolaryngoscopy. Proyecto ALBA expresses gratitude to AirAngel.org for sharing their designs, which helped them study the blade shape. After over 100 hours of work, they're freely sharing their models, encouraging others to print them at a cost that only recovers production expenses. It's time to join forces and make a difference together. Key printing parameters include: Material: PLA Wall thickness: At least 2 mm Infill percentage: At least 25% Supports: None Average speed: 50 mm/s Camera settings: Android Camera: 5.5, 7, and 8 mm for blade #4; 7mm for blades #1 and #2 Find Proyecto ALBA on www.facebook.com/ProyectoALBAMorelia.
