If you wear a Freestyle Libre 3, you've likely experienced false "compression lows"—waking up to urgent alarms simply because you rolled over and put direct pressure on the sensor.
This remix acts as a rigid arch over the Libre 3 node. It transfers external force away from the sensor and distributes it evenly across the surrounding skin.
Key Features
Zero Sensor Contact: Steeper conical shape ensures even heavy pressure won't push the shield into the transmitter.
Load-Spreading Base: Expands the footprint to distribute force, stopping the sensor from embedding into arm tissue during sleep.
Patch-Friendly: Features a smooth, low-profile outer rim that works seamlessly with thin, flexible, breathable patches (like Jinyu-Sega) without trapping moisture underneath.
Recommended Print Settings
Material: PETG recommended (durable, smooth against skin, holds rigidity under load).
Layer Height: 0.16mm or 0.20mm (smooth finish against skin).
Walls / Perimeters: 3 to 4 (ensures the cone is completely solid).
Infill: 15% – 20% (Gyroid).
Supports: None needed.
Usage
Place the cover directly over your applied Libre 3 sensor, then center your favorite breathable patch over the top to secure it.
