Helix Replacement for Portable Tire Inflator, Jump Starter and Power Bank

The original part broke (photo in white color)

We made some change regard to the original piece, we grow thicker the base and we add fillets in the helix to prevent break them

It's recommendable 3D print it with heat resistant material because when the motor is rotate, it generate heat therefore when the piece was thin, this was deformed but with more thick now it doesn't deform

Remember probe the tolerance to the motor arrow and the supports are necessary because the curve prevent the piece crash the the motor screws
