Windowsill shadow art. Set it on a windowsill or a shelf near a lamp, where afternoon sun turns its shadow on the wall into a hot air balloon. By day it sits as a small cupcake sculpture; at the right hour it becomes a second scene for anyone glancing at your desk or kitchen counter. A fitting shelf piece for a baker, a balloon fan, or anyone who likes a quiet visual trick.

Light does the rest. Set the frosting piece onto its post and light does the transmission: sun crossing the gap beneath the swirl's narrow neck slips past, while its wide crown blocks the rest, throwing a round canopy shape onto the wall above a slim basket shape below it.

Two pieces, one peg join. The set comes as two pieces: a flat base panel with a scalloped bottom edge, and a blocky, stepped swirl piece shaped like lifted frosting. A slim post cast into the top of the base panel presses into a socket in the swirl's underside, holding it a finger's width above the panel. No glue, no tools.

Small enough for a sill. Stands 4.7 inches tall in PETG, with crisp, even print layer lines across every stepped face of the swirl. The base panel runs a slim 0.92 inches thick, thin enough to cast a sharp-edged shadow, its scalloped bottom edge finished clean with no rough seams.
