There are 2 cereal containers (Narrow and Wide), check the above video to distinguish the differences:

The volume of both containers is 4 liters (16.9 Cups, 135.3oz). DO NOT GET the smaller versions!

Using regular 608 ZZ (or 2RS) skateboard bearings:

pack of 10: [link] (https://geni.us/uLMvbQ) or pack of 100: [link] (https://geni.us/OiChoH)

PTFE tube and connectors. I recommend 3mm ID / 4mm OD, but you can also use regular 2mm ID / 4mm OD (ID - Inner Diameter, OD - Outer Diameter)

3mm ID / 4mm OD: [link] (https://geni.us/NIfXBG4) 2mm ID / 4mm OD: [link] (https://geni.us/4YjDen) PTFE M10 Connector: link

Silica Beads:

the best are Molecular Sieve beads [link] (https://amzn.to/3jljvU9) More details about which method is the best silica beads with no markers: [link] (https://geni.us/ktHdsU) I recommend using silica with no color markers, the ones which are blue or orange are slightly toxic

Hygrometer (the square version, not round): [link] (https://geni.us/gAhF3) Dimensions: 46mm x 27mm / 1.81 x 1.06 inch.

Printing details:

• no supports needed!
• can easily be printed from PLA (try to use quality PLA), otherwise go with PETG.
• 0.2mm layer height for better quality, but also 0.3mm layer height works fine (lower quality)
• 3 perimeters (for strength)
• 100% infill (there’s a very tiny difference in overall quantity)
• you need in Total around 67 grams on PLA, for one complete set.
• you can print is on small beds like Prusa Mini 18x18cm (you only need to rotate the Main Body 45 degrees)
