Dry fuel container

In my area, dry fuel is produced in the form of tablets with a diameter of 40 and a height of 10 millimeters. The usual packaging of this product is inconvenient to use outdoors. So I created a screw top container for four of these dry fuel pills. The useful volume is a cylinder with a diameter of 42 and a height of 40 mm. A three-start thread is used. The model uses large enough gaps so that there should be no problems when printing. Fusion 360 source file included.
