$8.00Turboshaft Engine, with Radial Compressor and Turbine - Cutaway

myminifactory

I created a working model of a turboshaft engine that utilizes a radial compressor and a radial turbine using a vacuum cleaner as a reference point beforehand. This is the completely cutaway design of it. A key features of this engine include: ① Radial compressor (Impeller), Diffuser ② Radial turbine rotor, Turbine nozzle ③ Planetary reduction gears ④ Output shaft ⑤ Every single shaft uses no metal bearing. B. An Assembly Manual is provided in PDF format, consisting of 16 pages total. The detailed assembly manual includes a parts list, after-printing treatment instructions, and an assembly procedure based on standard skills such as filing, drilling, tapping, and painting. C. To purchase the necessary components, you will need: 1. Screws: M1.4x3.5L, M2x4L, M2x15L, M3x8L, M3x80L 2. Other materials: φ1x7L Piano Wire,φ5x110L AL Pipe D. STL files are included, totaling 39 items including a stand and tools. Almost all parts have been redesigned for this specific purpose, with the last two digits of the file name denoting "With Support" specifically designed parts. E. Estimated total net print time: approximately 64 hours (estimated based on PLA material, 0.4mm nozzle, 0.2mm layer height, 40% infill, and no raft or support). Note that printing settings such as raft, support, layer height, and infill can be adjusted according to your experience. F. Printing settings used for my models were "idbox" with a 0.4 nozzle and 1.75 PLA material. I wish you great success in printing this engine model. [Update20190528] Sun-Gear & Manual revised
