Made this 3-in-1 sewing tool for my wife and she finds it very handy. Functions are:

1) Point turner to push out sewn corners after turning right side out

2) Seam smoother to open and flatten sewn edges

3) Needle inserter to hold the sewing machine needle in place while tightening

The profile uses the 0.2mm Strength profile with 6 walls and infill increased to 50%. Also added top layer ironing.
