CNC tool length sensor / tool setter

# Simple DIY Tool Length Sensor (Bit-Safe Design)Protect your expensive endmills with this ultra-simple, 3D-printable Tool Length Sensor (Z-Probe). Unlike solid metal probes, this design is "bit-safe"—if something goes wrong during the probing cycle, the 3D-printed part will deform or break before your carbide bit does.It is designed for any CNC machine (like the 6040z) and works perfectly with Estlcam, GRBL, Mach3, or LinuxCNC.---## ✨ Features* **Tool Protection:** The plastic body acts as a mechanical fuse, preventing bit breakage.* **Easy to Build:** Uses common aluminum tape as the conductive surface.* **High Precision:** Provides consistent offset readings once calibrated.* **Low Profile:** Minimal height to maximize your Z-travel.---## 🛠️ Required MaterialsTo assemble the sensor, you will need:### 1. Conductive Surface (Aluminum Tape)* Amazon* Aliexpress### 2. Mounting Hardware (M3 x 12mm Screw & Nut)* Amazon* Aliexpress### 3. Wiring* A simple strand of wire to connect t
