About this 3D model

I am a designer of the following "Turboprop Engine". https://cults3d.com/en/3d-model/tool/turboprop-engine I re-designed the New Reduction Gear Assy for cost reduction of the metal ball bearings. This modification is fully interchangeable to original Assy. Bearing quanty is reduced to 1 from 8. Modified parts with reason are shown in photo with related original parts. - STL files (6 files modified): See photo. - φ3 x 26 AL Tube (3ea) are used as gearshaft. - Assembly Sequence and Points with "NOTE": See photo. - 3D printing settings: For Gears, 100% in-fill is recommended. Still this is not the model to print and assemble easily, I hope your perseverance too. Thank you for your interest.
