Turbo Charger Model [Working]

thingiverse

This is an operational Turbo Charger Model! It doesn't compress air, but it definitely produces a turbo sound! Just order all the parts and start assembling! Be warned, though: this device is quite large. To complete assembly, you'll need two 608ZZ ball bearings (https://www.amazon.com/gp/product/B00OKXRJBG/ref=oh_aui_search_detailpage?ie=UTF8&psc=1). As for the axle, I went to my local hardware store and bought some square aluminum tubing with a 4x4 mm profile. You'll only need about 8-10 inches of it for assembly. I also found flexible plastic tubing that helps keep things lined up properly as a stand-off. If you have any questions, feel free to comment! I'll release .IPT files upon request. Don't print the "Full Assembly DO NOT PRINT.stl" file; it's just for reference during assembly. Also: the motor I used was the High-Speed Motor from Radioshack (https://www.radioshack.com/products/radioshack-super-speed-9-18vdc-hobby-motor?variant=5717369029). Keep it at about 12 volts, though - higher than that and things will melt quickly. Known Issues: The gear for the motor needs a better way to attach to the motor itself. There's also no place on the base for a switch. Printer Settings: I used a MakerBot Replicator (5th Generation) printer. You can print without rafts if you want, but it doesn't make a difference. I set my resolution to .18 and infill to 50%. Notes: I only supported the conical half of the turbo shell because there's a weird dip in it that would cause air to leak out. I tried to use at least three or five layers to keep everything sealed up tight. You can see from the thumbnail that there's a hose clamp around the output of the turbo - this is due to some warping during the print, and it shouldn't be necessary.
