Cereal Dry Box – Hygrometer - SKROAM WILDONE PRAKI

New: Perfect Fit" for SKROAM / WILDONE / PRAKI Containers

New: Just added a slotted version for improved desiccant ventilation.

Following many requests from the community, I have designed several models for cereal boxes. While my original designs are compatible with most containers found on Amazon, their universal fit sometimes means they aren't perfectly snug for every specific brand. To provide the best experience, I’ve developed this new "perfect fit" variant specifically tailored for SKROAM type boxes.

This model allows you to store your filament spools in airtight containers to prevent them from absorbing moisture from the air.

It can accommodate a rectangular hygrometer to monitor humidity levels.

Thanks to the integrated rollers, you can print directly from the box while keeping the spool protected inside.

I've added a new variant featuring slotted walls & bottom — ideal if you want better airflow around your desiccant

Spool compatibility: Spools From 50 to 70 mm wide

This model is compatible with the following “cereal boxes,” available on Amazon: SKROAM, PRAKI, WILDONE. 

Use a 4mm hexagonal, allen wrench to screw the rollers. Tip: To allow the rollers to spin freely, tighten the screw all the way in (but not too tight, as it’s plastic, not metal), then slightly loosen it (about a quarter turn) until the roller turns smoothly without resistance.

If you need the labels : Labels Here !

608 Bearings ? I didn’t include the spacers in this model (it would complicate the description for most users who don’t want bearings), but I plan to add them a bit later. For now, you can use the four spacers included in the print profile of my older model: https://makerworld.com/en/models/215704-dry-box-cereal-box-spool-hygrometer#profileId-234889

If you want to print directly from the cereal box, you will need a lid that allows the filament to pass through.

Note: Since my very first model, and following user requests, I have created several variants (round or rectangular hygrometers, with or without rollers, plastic rollers or ball bearings, with or without labels, etc.). I have tested and personally use all of these models; they all work perfectly and, objectively, none is better than another. It mainly comes down to personal preference or specific needs. I understand that it can be easy to get lost among all these models (I’m starting to get lost myself too 🙂). I plan to create a comparison table to help everyone choose the model that best suits their needs.

A note on print quality: I test all my models before uploading. If your print doesn't turn out well, check your filament (old? wet?) and printer calibration first. Most issues come from these, not the model.
