Frost Bite is a compact everyday carry keychain tool designed to pop beverage pull tabs without tearing up your fingernails. The bottom slot slides directly over standard soda and beer can tabs, giving you clean upward leverage with practically zero effort.

I designed it from scratch in OpenSCAD with a slim 5 mm profile so it rides flat in your pocket without adding bulk. The keyring loop is reinforced to handle daily pocket carry, and the internal tab slot is tuned to bridge cleanly on standard 0.4 mm setups so you can print it flat on the bed with zero supports.

Files are open-source and customizable via OpenSCAD under the Cold Front Forge project.

EDITIONS & FILES

Single Color: Debossed snowflake emblem. Prints in a single run with standard single-extruder setups.
Multi-Color Flush: Inlaid two-tone snowflake that sits completely smooth with the top face.
Multi-Color Embossed: Two-tone snowflake raised 0.6 mm above the top surface for tactile contrast.

If you are loading raw STLs instead of opening the pre-sliced 3MF project in Creality Print, import the body and snowflake files together as a single multi-part object to keep coordinates aligned.

RECOMMENDED PRINT SETTINGS

Orientation: Flat on the build plate, face up (no supports needed).
Material: PETG or PLA+ recommended for strength under leverage (standard PLA works for casual use).
Layer Height: 0.20 mm.
Walls: 4 walls (critical for mechanical strength along the tab slot and keyring eyelet).
Top / Bottom Shells: 5 top layers, 4 bottom layers.
Infill: 25%–30% Gyroid.

MULTI-COLOR NOTES (AMS / CFS)

Enable prime tower (35 mm width recommended).
Enable "No sparse layers" to avoid unnecessary priming while the base body prints.
Set dark-to-light flushing volumes high enough to prevent dark filament bleed into lighter snowflake accents.
