Pulley system to Frax3D ventilator 2.0 - Ambu
thingiverse
A high-torque to high-speed conversion system is being developed for Frax3D, utilizing a pulley design that leverages the strength of stepper motors. Images showcase the printed pulleys integrated with the Frax3D structure. Feel free to review and provide feedback if you notice any flaws in this ongoing project. This design may evolve over time as it remains a work-in-progress. A separate open-source respirator project is currently underway, accessible at "rspidr.blogspot.com" (English translation). A note has been added for the "V3-X_MRB+endstopsup.stl" support, designed to accommodate a makerbot "Mech Endstop v1.2" within the Frax3D framework. Credit goes to joelfrax for the original design inspiration. Details on the required materials are listed below: Printed parts: - "Frax3D ventilator 2.0 - Ambu" (excluding "V3-6.stl") - V3-6_MRB+substitute.stl - V3-11_MRB+pulley150.stl - V3-12_MRB+pulley36.stl - V3-13_MRB+disk.stl - V3-X_MRB+endstopsup.stl Fasteners: - 8mm screw rod, 15mm length with nut - 8x M3 x 16mm bolts - 8x M3 nuts - 1x M2.5 x 16mm bolt - 1x M2.5 nut - (1x M3 x 8mm and M3 nut or 1x M2.5 x 8mm and M2.5 nut) - 3x M4 x 30mm bolts - 6x M4 nuts Additional components: - GT2 2mm (400mm) belt
