# Wanhao I3 Duplicator BLTouch Bracket
# Summary
When I was upgrading my Wanhao Duplicator I3, I looked into adding bed levelling to the printer. To do this, I used the BLTouch unit and upgraded the Wanhaos firmware to incorporate this sensor. Doing this, I found that none of the Thingiverse BLTouch mounts fitted my specific printer due to the metal bracket being longer than the usual bracket. So I redesigned the frame and created the one shown above and below.
# Marlin Firmware Probe Offsets
```C
#define X_PROBE_OFFSET_FROM_EXTRUDER 52 // X offset: -left +right [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER -46 // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER -2.72 // Z offset: -below +above [the nozzle]
```
