Adjustable Doorway Clamp for Baby Swing

My baby girl likes to swing. Not rock, not be still, swing. Using her car seat and the arm pendulum method was getting exhausting so I designed this clamp to fit on the top (and sides) of an indoor doorway threshold.

Sizing: Measure the height of the perimeter panel (moulding) on your door and pick the model with at least that long of a grip. Look at the pictures to see how to use screws to adjust down to the size of the doorway.

The clamp is ridiculously strong, i was able to hang my body weight on it. We'll be using it as she grows into a toddler size swing. I could see this being used for a workout tool. (I printed in high quality PLA with 8 perimeters and 20% infill.)
