A simple container for silica gel that can be put into a filament box or vacuum pack.

Print in spiral vase with layer height of 0.3 mm. This creates a lot of tiny gaps in the wall so the air can circulate through. With a layer height of 0.2 the walls will be air tight which is not suitable for a silica gel container. A layer height of 0.4 caused print issues for me.

Due to its round shape and the rough pattern the ball is very sturdy, even when it only weights 3 gram. It can be squeezed a little bit to fit the cap on it which then sits very reliable on the ball to keep the silica gel inside.
