Main-Gear-Box, for Helicopter, Full metal bearing type

cults3d

This model is a customized version of the Main-Gear-Box, originally created on Cults3D. The modification aims to utilize major components from the Helicopter-Power-Train model, which runs on a Turboshaft engine. To achieve stable rotation, several key changes have been implemented: 1. Metal bearings are used for all rotational shafts. 2. The input gear has been replaced with a bevel gear. 3. Provisions have been made to attach the Main Rotor Head in future updates. A comprehensive assembly manual is available in PDF format (14 pages). This guide includes detailed instructions on parts preparation, printing treatment, and assembly procedures based on Standard Skill levels (filing, drilling, tapping, and painting). Downloadable files include STL models for 24 components, with "ws" indicating the presence of special support designs. Purchase information is provided for essential parts: * Metal bearings: Used for every shaft; estimated cost in Japan is approximately ¥6,000 per set. * ABS tubes * Screws and other hardware (e.g., M1.4x3.5L micro screws) The estimated total print time is around 35 hours, assuming PLA material, a 0.4mm nozzle, 0.2mm layer height, 40% infill, no raft or support. Please note that actual print parameters may be adjusted based on individual experience. Wishing you success with your project! **Update (2018-07-28)**: Part information in the assembly manual has been revised. **Update (2020-02-20)**: No special support parts have been added at the request of a purchaser.
