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)
Image below is for reverse bowden adapters:
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)
Upcoming:
bambu hotend mod compatibility

Official release | Changes |
---|---|
v5 | First official release |
v20 | Multiple optimizations integrated |
v21 | Added beacon/cartographer support |
v22 | Optimized overhangs for beacon/carto mount Eliminated thin walls at the led internal routing and side screws Optimized led routing path, removed some bad geometries |
v23 24th June 2024 | Optimized fan clearance Removed redundant adxl mount (the screw holes near the nozzle is the new position) |
v24 12th July 2024 | Added proper heatsink airflow ducting for plus/max models Reverse bowden adapters No changes to N4/N4Pro design, the required mount for reverse bowden has been there since the first version |

v26 13th July 2024 | Fixed mesh error caused by v25 |
v36 14th July 2024 | Reworked front looks, preparing for cosmetics More cooling holes for extruder motor Added tensioner key hole (remove right fan to access) Reworked side mounting posts Corrected adxl hole spacing |
v37 19 July 2024 | Added wiring route for Beacon/Carto (Use zip-ties) Updated to UBBI v87 |
v37.1 3rd August 2024 | Updated to UBBI v90 Added ECAS04 support Shortened reverse bowden by 1mm |
v49 25th October 2024 | Corrected probe mounting location Corrected side mounting hole offset Corrected carto mounting position (same xy offset, different z offset) Pushed front fan 1mm forward bambulabs hotend support coming soon |
The author remixed this model.
Added 2 mounting holes and 2 alignment holes up top for reverse bowden capability, 2 more holes below for endoscope/light mounts
