Toadstool — twist-open bonbon capsule

A tiny Amanita-muscaria toadstool that twists open to hide a wrapped

bonbon or candy inside. The red spotted cap is a screw-off roof; lift it and

a clean toadstool stalk is revealed — an Amanita skirt ring and a **soft

volva bulb** at the base — with a hollow chamber for a treat.

Designed to the 2.7-inch (68.6 mm) BONBON capsule: closed it is

Ø46 × 52 mm with a min bounding sphere of Ø58 mm, so it drops into the

capsule with room to spare.

Printing

• Body: flat base on the bed, collar up. No supports.

• - Cap: wide rim on the bed, dome up (narrows to the apex → zero overhangs,

•   spots face up). No supports.

• - 0.2 mm layers, 3 walls. All walls ≥1.5 mm; the coarse 3 mm-pitch thread

•   prints clean at 0.2 mm.

Using it

1. Twist the cap on once to seat the threads (2–3 turns, snug not tight).

2. 2. Drop a wrapped candy (≤ Ø24 mm through the neck; chamber holds ~Ø28 mm).

3. 3. Screw the mushroom roof back on. Surprise sealed. 🍄
