This is a container to put silica beads in the two bottom, built in areas of the Bambu AMS. There are other models available but I wanted to make one that took advantage of every available space possible. There are also holes in the front and back of the opening that I wanted to take advantage of any air flow. These should print well at .16, but I don't mind the extra time at .12. I wanted to make a container that snapped shut before filling the silica instead of snapping together after filling silica. The rear door slide on with the side steps to the rear (See Pic). The holes in the top also line up exactly with the AMS Cover. I hope everyone enjoys these!
