🧊 Stanley Bottle Ice Ring — Hollow Cylinder Ice Mold

The perfect ice mold for your Stanley wide-mouth bottle — no more stuck cubes, no more waiting forever for ice!

This custom-designed hollow cylinder creates donut-shaped ice rings that slide effortlessly in and out of wide-mouth Stanley (and similar) bottles. The unique annular design drastically increases surface area, meaning ice freezes 2–3x faster than solid blocks — and cools your drink from the inside and out!

Designed for 2mm wall thickness — the ideal balance of strength, speed, and material efficiency. Prints quickly, uses minimal filament, and fits perfectly inside standard Stanley wide-mouth bottles.

✅ No more jamming — sized to slide freely, no fighting stuck ice cubes

✅ Ultra-fast freezing — thin walls + hollow center = ice in ~30–45 mins at -20°C

✅ Maximum cooling — large surface area chills drinks fast

✅ Stackable & nestable — make multiple, they store neatly in the freezer

✅ Food-safe & durable — perfect for PETG or flexible TPU for instant ice release

✅ Simple, no-fuss design — easy to print, easy to use, easy to clean

Usage: Fill with water (leave small gap for expansion), freeze, drop into bottle. Works perfectly for daily use, hiking, camping, or the office. Make 2–3 and rotate them — one in use, one freezing, one ready to go!

Dimensions: Sized for standard wide-mouth Stanley bottles — adjust scale in slicer for other brands.
