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.)
