A faceplate model for the Neptune 3 Plus. Most likely will work for the 4 plus as well. Designed to be printed in three parts where the center part will clamp down and join the three pieces when mounted. 

Faceplate would be perfect to modify and add custom ports or to just use completely enclosed, as I use it. Center plate can be easily modified to add your own design.

Neptune 3 Plus Faceplate / Frontend

NeptuneFacelate - Center  v4.3mf

Plate for the underside of your Neptune 3 plus (probably 4 plus as well) to mount a BTT Octopus to. Will need to dremel/remove two of the old motherboard studs, one of the cover studs, and a tie-down point. Fairly easy process but be careful and take it slow as the stud are actually seem pressed through the base sheet metal and not fully welded. So you may end up with slight imperfections topside of the unit if the two pieces separate while dremeling. (see pic) Fan must also be moved to other side of plate, cooling performance is still sufficient for default setup but if expanded a new solution may be needed.

Chain system for the Neptune 3 plus, would probably work for 4 plus as well. Designed on the popular chain series: https://www.thingiverse.com/thing:6305733
But modified to be smaller chains that fit the bed cable. 

System is meant to be used with silicone spacers and used with specific bed harness. 
I used: https://www.printables.com/model/484701-neptune-3-pro-bed-harness-support/files
but other ones may work assuming the pegs are in the correct position. 

Connects to frame using existing extrusion screws and mounts into through hole. 
Will need to remove existing through hole relief piece, most likely resulting in its destruction.

Used zip ties to increase rigidness. I would say its a necessity for now until it annoys me enough to redesign.

Bracket designed to move adjustable desk controls back and down slightly to be completely under the desk and not prone to being bumped into. 

Bracket is designed to only need the included desk screws. The bracket itself is held in place with pressure connections in the model. Seems to work well but it is my first attempt at such a fastener. Printed with 15% infill in PLA.

Adjustable Desk Control Relocation Bracket

desk model v4.3mf

Simple desk mount for all things that connect through a 12mm rod these usually include mics, task lamps, tablet and phone holders, etc. Designed to just slide over a 15mm desk, which are common now with new budget adjustable desk options. 

I printed it with 20% infill and seems pretty sturdy but I would not load it too much. Mounted iPad with no problems. Mount stays on more rigidly if you place small piece of double-stick tape on top to give a little adhesion.

Just another tool holder for the Neptune platform. 
Able to holder a glue stick, scraper, side cutter, reamer, xacto knife, calipers, and usb.
Clips right into extrusion, when mounting be careful of area near scraper as could break if forced in.

These set of models do a few things, One the chain connector model allows for the popular Neptune link and chain guide to be mounted to the linear rail plate from the TBStron3D linear rail upgrade kits. Should be applicable to all kits but I've only tested the 3 plus one. 

The adapter utilizes tapered m3x12 screws that came extra with my kits. But could be easily remodeled to accept different m3 sizes. main thing is you would want about 5mm of screw poking out the bottom

Second the arms and sensor cover move the filament run-out sensor to be directly placed over the extruder. Mainly shifted this to allow for more filament to be used at the end of the spool before the sensor is triggered. The metal plate on the sensor does need to be removed to slot the rest of the assembly in. 

The wiring does need to be moved if you would like this orientation, about a 12" extension to the wire is needed. I cut and soldered the extension in my case. 

The chain adapter will function stand-alone but the sensor cover will not due to it needing to be mounted to the adapter. 

Adapter is built on the link and chain model: https://www.thingiverse.com/thing:6305733

Slightly unique extruder cover for the neptune 3 pro / 4 extruder that works with the wind warden blower:

Built on the official wind warden cover: https://www.printables.com/model/626710-fanflow-fortress-cover-for-windwarden-upgrade-eleg

Modified the design to have a more symmetrical shape and added screw point for rigid mounting.

Neptune WindWarden Extruder Cover

Case to hold the Freenove 5" touchscreen case and a raspberry pi4B with 30mm fan. The case mounts to the side extrusion. The pi remains mounted to the screen and slots in as one. I used a microsd extension cable with a ribbon cable routing between the screen and pi to allow for microsd to be access without teardown. 

Model builds on Alcarria3D Freenove case but changes just about everything. https://www.thingiverse.com/thing:6442906

To install:
-Mount 30mm fan into case
-Mount raspberry pi to back of Freenove Screen 
-Route microsd expansion chip and ribbon cable between the screen and pi
-insert button into case
-slowly slot in screen/pi assembly into case (dont fully seat yet)
-align microsd card into position in case partway
-allow assembly to sit and screw in microsd expansion card 
-Mount cover onto case and screw
-screw down the assembly by running screws through the case to the screens open mounting nuts (optional as cover will hold assembly together just fine


Parts Used:
-Raspberry pi 4B: https://amz.run/8kAt
-Freenove 5" touchscreen: https://amz.run/8kAs
-microsd Extender: https://amz.run/8kAr
-longer ribbon cables for extender: https://amz.run/8kAu
-Screws for cover: m3 x 5 (need to source)
-Screws for screen: 4 slots in case but I used only 2 screws that came with the screen
-Screws for microsd expansion card: used the ones that came with the expansion cards.

Screen will display horizontally by default. 
will need to modify config file on the microsd card to change:
