This is a desiccant capsule for loose silicagel,  that the enthusiastic 3D-printing person owns. The capsule fits in the Phonak/AudioNova hearing aid charging base. But it can also be used to replace other one-way-capsules with desiccant. 

Diameter 31 mm, height 11 mm

Printed in PLA with 0.4mm nozzle, layer height 0.2 mm, line widh 0.4 mm

Slicer settings for both objects needs to be different. 

The lid has to be printed without top/bottom shells. I used 6 wall loops for a sturdy frame. Sparse Infill pattern has to be set as Rectilinear, with a density of 30-50% (I chose 40%). I had set speed down to 60 mm/s for the lid-infill.

The capsule is printed with standard-settings. I recommend "Archimedean Chords" as top- and bottom surface pattern. Concentric has ugly seams, and the other options are too shakey ;-)
