Corkscrew Drive Propeller with Three Blade Styles

prusaprinters

Pick your favorite style of propeller and size, and then enjoy launching them using the power of a corkscrew drive - either across the room indoors, or high into the sky outside!An easy print that requires no supports or brim, and the corkscrew is designed just small enough to even print on my Prusa Mini (it's just under 17 cm tall).  Recommend setting the “Vertical Shells → Perimeters” value to at least 5 for extra strength for the “corkscrew” and “push knob” parts.  Depending on how much your setup wiggles or filament flexes, you may find that reducing your print speed to 50% will help the corkscrew print well all the way to the top.For your convenience, I've attached a 3MF file that includes all of the propeller styles & sizes, so that you can simply show/hide the one you'd like to print.  If you're not sure which to choose, I'd recommend starting with the 140 mm “Ringed Propeller”, but the others are fun too.  (Note that the propellers are all optimized for a .4 mm nozzle size, but if you'd like a .6 mm or other version - just let me know in the comments.)My kids and I had a lot of fun experimenting with different styles of propellers and seeing which worked best for both outdoor and indoor flight, and we hope you'll enjoy as well!  Here's a quick video showing how my son can easily fly it horizontally across a large room with ease:
