About this 3D model

The Sentro sewing machine my mom's volunteer organization uses breaks a lot. The gears break even more, but you can buy that model on Cults. Here is the handle, which eventually breaks, I'm told. I haven't tried or fitted it yet, but she'll get back to me and let me know if it fits. (This is designed to fit the original screw cap + rotating ball handle). Unfortunately, due to the original design, you'll need a lot of supports. Print hollow side down with supports.
