Mini edible oil barrels—perfect for use as hamster toys, miniature decorative pieces, or clever hidden message containers.

A few key tips:

1. Both the barrel body and the oil reservoir must be made from transparent materials to achieve the desired effect.

2. Begin by printing the oil reservoir first, then secure it in place with adhesive to form a seamless, transparent cylinder.

3. During the second print pass for the barrel body, set the printer to pause at around 60% completion. At this point, carefully snap the pre‑assembled oil reservoir into position, ensuring it rests snugly against the bottom of the barrel, then resume printing.

4. Once the pull ring and bottle cap are in place, press them firmly into position—be mindful of the orientation of the pull ring, as both steps are one‑time actions.

5. To enhance transparency, simply search on Bilibili for “Bilizhu polishing” tutorials: after immersing the barrel in Bilizhu solution, allow it to dry completely.

For the candle lamp version, embed a candle lamp base into the bottom of the barrel. If the lamp comes with a lid, remove the base—but leave the lid intact.

To assemble, print the barrel body halfway, insert the oil reservoir, then finalize by embedding the lamp base—your masterpiece is complete! (The official candle lamp designs vary slightly between versions; the diameters should be roughly the same, so you can easily fit the base into the pre‑drilled hole—and if it’s a bit loose, apply a small amount of 502 glue to secure it.)
