Completely hypothetically and with no ability to put any of this into action -
You could gut the Nomad and replace the internals with those from one of those tiny little plug and play Megadrives.
That tiny Megadrive can be modded to accept a cart slot.
This would leave most of the Nomad internals free for a stripped down 32X.
The main issue there would be whether or not those plug and play Megadrives have the ability for 32X add on - the Sega Genesis 3 doesn't, so probably not.
Oooh! You could gut and strip down a CDX as that supports a 32X (gotta love the shamless destroying of important pieces of videogame history by the way!
).
Then again, if you're doing that, you might as well just use the Nomad as the boards are probably the same (and I'm pretty sure that supports the 32X)
Okay this is impossible. Empty Nomad shell and Raspberry PI it is 0 -

It's a really lovely design alright. I think it's my favourite Sega have ever put out after the Megadrive Mark 1.
Honestly? I could never see the appeal of the Neptune from a hardware or aesthetic point of view.
It's a MD2 with cosmetic surgery and a partial lobotomy - no Master System backwards compatibility or SegaCD/MegaCD compatibility.
Its like reducing a Gundam action figure to Malibu Stacy, and giving it a hat. I almost find it offensive!

Your completely missing the point, it's a Sega console that was never released. It's automatically cool without even having to try0 -

Yeah. But my point is, Sega weren't even trying. :P
OK, I may have been a little harsh on the Neptune. But it just wasn't a step forward for either hardware that helped sell better games or an improvement in console case aesthetics.
Frankly its getting too much love at the expense of VR.
Imagine that combined in an arcade with an R360.0 -

I don't think so, had the 32X not have seen the light of day then the Neptune would have been the natural bridge between the Megadrive & Saturn. It really should have been the way to go rather than using an add on component, another psu, link cables at the rear etc...your certainly right in that Sega wern't thinking!
But being 32 bit, & the Saturn being 32 bit...Sega were stuck between a rock and a hard place really.0 -

So, if anyone comes across a 3d model of this thing let me know and I'll see what i can whip up.
I've had a bit of a look on google and I cant find a 3D model of it.
Couple of questions:
(for SteveSI)
What file format do you need the data in?
What's the maximum size your printer can handle for components (width by depth by build high (supported by scaffolding)?
Open question:
Can anyone provide the 32X cart's slot size?
I might have a go, I've enough reference images to give it a shot.

Right.
This is the thing I'm looking for measurements on.
Actually, this is PAL Sega MegaDrive's/Genesis' one. I'm looking for the 32x's carts measurements. Right now I only need:- the total length from one end to the other
- the total from front to back
If anyone could take a ruler to one of their carts this would be a big help with working out the rest of how big the Neptune should be (this slot and the controller ports are the only scale references I've to work with, and the controller ports are less that ideal).
Oh and in millimetres would be nice too!

• Build envelope: 225 x145 x150 millimetres/8.9 x 5.7 x 5.9 inches
• Build Volume: 5 litres
Layer thickness: .2 to .3mm
The file format ideally would be fully formed valid .stl but I can work with pretty much any format.
This vid might give you an idea of what can be printed.

The Neptune supposedly used the same base at the Mega drive 2 so should provide some reference measurements as well.
Great! Thanks for the dimensions!
Though I don't own a MegaDrive 2... :rolleyes:
Well, I was never expecting this to go smoothly. If I can dig up the width and height all the better.• Build envelope: 225 x145 x150 millimetres/8.9 x 5.7 x 5.9 inches

Well neither the build volume nor the layer thickness should be problems since the casing is hollow and may only need fine tolerance at the joints.
I dunno with the width by depth of a MegaDrive 2 is less than 225 x145 mm. If it isn't, it'll mean splitting the case into joining parts for printing.
I don't expect the valid .STL to be a problem, I've done that before for a CNC operated mill (it only accepted floppy disks. No lie)
The stuff you've printed before on this, did the print vary much from the file's dimensions? Did the printer scale it up automatically to allow for sanding down to spec'ed size?0 -
