Insert for Sunlu 3rd generation reusable spools that allow you to dry your dessicant (silica gel) in a spool dryer.

I use (and recommend) using organza bags for your silica gel. The hole pattern on the insert matches the pattern on the spool - 1.85 mm. So as long your beads are at least 2 mm, they should stay in. Though it might be challenging to pour our beads out of the containers.

The diameter of the insert is 187 mm.

Printing

Don't forget to print in materials suitable for your drying temperature. Don't use PLA at all. PETG is fine as long you dry at 60 °C and have enough patience.
