fixed finger ring

thingiverse

I tried printing the Helicopter_fingerring.stl and realized that the shaft with threads isn't touching the build plate. It's almost 1 mm above the plate, and so is the finger ring. These issues caused the print to fail. Here are the original STL files for the blades and front, all together now. The original Flying Helicopter Toy by 3DBROOKLYN works well - these changes make it work even better for me. I cut the bottom of the tail so that the shaft touches the build plate, and added some material to the finger ring so it touches too. I've had good luck printing at about 125% scaling. I sliced in PrusaSlicer and printed on an Ender 5. Here are my actual scaling factors: Settings for each part: Helicopter_blades.stl: 125% scale all axes Helicopter_Front.stl: 125% scale all axes fixed finger ring V1.stl: 124% X, 124% Y, 123% Z My printers are all well-calibrated and I used a value of -.09 for XY Size Compensation. First Layer Height is .35. Layer height is .2. Two Perimeters (walls) will do the trick. Three top and bottom layers should be fine. On the Helicopter blade, one Perimeter (wall) made it much lighter and fly better. You may need to play with some settings depending on your printer and slicer, but this toy works great when you get it right.
