Features:
- Compatible with all neptune 4 models
- Optimized overhang performance vastly
- Easy support placement
- Supports ECAS04/PC4-M10/UBBI reverse bowden adapters
- Smoother heatbreak air duct
- Optimized part cooling air duct
- M3 (4.5mm outer diameter, 4mm deep) heatset inserts
- Added mounting holes for reverse bowden/endo cam - adxl (intended use, can add anything else)
- Beacon/cartographer support
- BTT Eddy adapter here
- Runout sensor on print head here

For Beacon/Cartographer model:
- x offset: 0
- y offset: 22
- As designed in CAD model (for more accuracy, please use a caliper for measurements!

NOTE:
Some reports stated that Winsinn fans may not work as heatsink fan since it will interfere with the extruder motor's magnets.
FIX: Tape a 24mm washer to the back of the fan

Recommended replacements:
- Sunon VX A99
- TriangleLabs

The first 3-4 snaps for UBBI must be done with a wrench, to break in the mechanism before it gets soft enough to be used by hands!

Recommended print settings:
- Nozzle diameter: 0.4mm
- Layer height: ≤ 0.2mm
- Reverse on odd: disabled
- Precise walls: enabled
- Wall order: i/o/i
- Print orientation: as imported
- Supports: as shown in picture (use paint bucket and click)

Recommended materials:
 - PETG
 - ABS/ASA
 - Any low creep, heat resistant materials

Error note: 13 heatset inserts in total and 14 for carto/beacon (6 fans, 2 adxl, 2 led, 2 reverse bowden, 1/2 probe)
