STFM case remake

[DoG]

...
What printer did you use, this enclosure is big !

Looks good, apart from the colour.

I was thinking about the pistorm and wondering how it could be fitted when the cpu is right at the front of the motherboard and space is tight.

I wonder if the back half of the case could be stretched by an inch so that the board can be fitted further back ?

It would spoil the elegant proportions but make expansion a lot easier.

There are many 68K extension boards available that can be used to move boards away from under the keyboard on certain STFM motherboards. In fact I think a few members on the forum have designed some.

Stretching the design takes it away from the original shape / size so I think that is not really an option with these extension boards out there.

Also the Phoenix H5 motherboard was designed with expansion in mind and is an ideal board for this case once it’s finished.

Unfortunately life has kind of got in the way of all my projects over the last year and things have slowed down. Am hoping to get back onto this after upgrading my 3D printer.

With all the measures and geometry already there, it should be relatively easy to design a spacer that goes in between the two case halves that then would still go together with longer screws?

I have pondered a vertically stretched case with an extension between the two halves but I don't think it would look good or be strong.

One problem with my front-back stretch idea is the vertical post that supports the keyboard passes through the motherboard.

The alternative is to continue the top, rear shape forward to the front, with strengthening and have a post which meets the keyboard support post to give the top case some more support in the middle. Maybe have troughs for brass rod to be epox'd in to add to the strength. Then create a shortened case to make an external keyboard enclosure in a similar manner to the one I made by chopping down an original case:

This would make a "two box" ST with plenty of space for expansions internally, as it's only really the keyboard which causes height issues.

@stephen_usher

You mean something like the DDD casing?:

Yes, but a smooth plastic shell. No need to relocate the floppy to the front or put the LEDs on it as they will be on the keyboard.

I found a full 3D model of Atari ST in CGTrader ($15)
https://www.cgtrader.com/3d-print-model ... rint-model

... I could have design my self, but ... the model existed !

Look like it is very accurate in dimension, it is a STEP file and I can modified if needed, I am fluant enough in CAD for some minor change.

Just need to build my "elongated printer", I have the parts of my old Printrbot, which should be perfect !
