Carousel Drawer Tower — swing-out organiser

A carousel organiser you build as tall as you like. Each tier carries a set of

open-top pie-wedge bins that drop onto pivot pins and swing out into open air, so

every bin is reachable from the top without unstacking anything. Swing a bin back

in and the tower closes into a clean fluted column.

- Stack any height — every tier is a self-contained module joined by a keyed spigot and socket.

- Won't tip — the base is a wide fillable dish. Pour in sand, steel shot or loose change, drop the base lid in on top, and the low heavy mass keeps the tower planted even with a loaded bin swung fully out.

- Reeded barrel-stave walls — the curved outer face of every bin is fluted, so the closed tower reads as a ring of columns.

- Prints flat, no supports — every part sits floor-down.

Footprint about 124 mm across, tier pitch 44 mm, 3 bins per tier by default.

★ WHAT'S IN THIS LISTING

- dish — wide ballast base bowl (print 1)

- base — base lid plus first hub, traps the ballast (print 1)

- hub — stacking post segment (print 1 per extra tier)

- bin — swing-out pie-wedge bin (print 3 per tier)

- cap — domed finial (print 1)

- Parametric OpenSCAD .scad source

A 3-tier tower like the photos = 1 dish, 1 base, 2 hubs, 9 bins, 1 cap.

★ PRINT SETTINGS

- All parts floor-down, no supports. dish = open bowl up, base = lid down / post up, hub = shelf down, bin = open top up, cap = socket down.

- 0.2 mm layers, 3 walls, 15% infill, PLA or PETG.

- Drop each bin onto its pin; the barbed pin head snaps over the bin barrel to retain it while it still swings freely.

★ FULLY PARAMETRIC

Open the .scad to change bin count, tier height, tower radius, flute count, pin fit, or stacking clearance. Part selector: dish / base / hub / bin / cap; tier_assembly / tower / open / exploded for previews.
