About this 3D model

Shuttlecocks tend to dry out in their storage rolls, which greatly reduces their lifespan. This lid with moist Hydro-bead elements provides constant moisture release, preventing premature drying and the associated reduction in ball life. Approx. 10 Hydro-beads (Pearl.de) are pressed into the upper hole. The entire lid is then immersed in water for a few hours so that the beads can absorb water. Afterwards, the lid can be placed on the badminton roll and the balls will be provided with a humid roll environment for several weeks, which increases the lifespan of the shuttlecocks. The opening for the Hydro-beads is 3.7mm in size. So, no significantly larger beads should be purchased. These beads should work.
