This is a remix of agepbiz's Pull Copter Finger Ring.
No assembly required! (Although you do need to remove some support material.)
I merged the ring and frame parts together, removed the no-longer-necessary screw holes, and changed some overhangs to optimize printing for the new orientation.
Because I had to change some of the overhang orientations, the copter_key (pull cord) needs to be mirrored from the original.
If you would like to use a longer pull cord, I recommend this one by Gered. Just make sure you mirror it in the slicer before you print it. (In PrusaSlicer, right click the model, go to “Mirror”, then click “Along X axis”.)
copter_ring_print-in-place.stl needs to be printed with supports. The auto-generated 'on build plate only' supports work just fine.
The 3MF file has the copter_ring_print-in-place, an unmodified copter_rotor, and a mirrored copter_key. It also has settings for supports on the copter_ring only.
The gcode is sliced directly from the 3MF with the default Prusament PETG profile.
The author remixed this model.
