Print using transparent PLA or PETG so you can take advantage of the color-changing silica beads. Slots are set at 1mm so that color-indicating, reusable silica gel beads do not fall out of the container. Amazon silica

It is designed to hold rectangular Digital Hygrometer LCD Monitors: purchased from Amazon.

It is not necessary to use supports. However, if you use your own print profile and want supports, make sure you use the setting so that the supports only print on the plate. If you try to use internal supports, they will be next to impossible to use and thus, your model will be next to useless.

When 3 units are installed in the AMS module with fresh silica beads, they all will initially read 10%. After a few days, the reading will increase as the silica gel starts to absorb moisture. Keep the AMS lid closed to maintain a sealed environment and thus minimize absorption of humidity from the air and it will lengthen the life of the silica beads.

When you slide in the lid, you have to push gently upwards so that the little 'bump' on the lid gets past the wall and securely closes the top.

I recommend that, unless you have just opened a fresh spool, before you mount your filament in the AMS, dry it out in the X1C or a stand-alone dryer. If your filament starts out ‘damp’, it will take a long time for the 3 silica pods to dry out your filament.
