About this 3D model
Here's a model of a screw top rugged travel container designed to hold up to 3 Tampons. The idea being you can keep this in your bag/luggage so they're handy and undamaged when needed. Note - after printing the screw threads will be very tight and feel like they're binding. This is normal for printed threads. You will need to slowly tighten and loosen the top a few times partway until it loosens.
