Sega Master System game shell for 3D printing

-- Latest version here --

I designed a simple Sega Master System game shell for 3D printing.
The shell fits Sega 28 and 32-pin single IC pcb and is designed to be easily printable.
(Scans of the target pcb https://www.smspower.org/forums/17935-OfficialSEGA28pinPcbScan )

I have provided STL files but if you want to compile the source to STL files your self, you will need OpenSCAD http://www.openscad.org/
And you will need 2 M3 screws, 10 to 15 mm long, to screw it together.

Beta 1
First public beta.

Beta 1.1
When I copied over the pcb holder from the front to the back, I forgot to change the height of them.

Release 1, Beta 1.2
Fixed some details, I find this version to work well and is easy to print.

I printed mine with the default settings in Prusa Slicer for my MK3.
Layer height was 0.3mm (Draft), in PETG and no supports since I designed it to not need it.
Currently it takes less than 3 hours to print a complete shell (2h40m according to the software)

Pictures of my print and I used my Columns pcb to show it of.

It looks good I was thinking about doing this as well but using an SLA 3D printer The layer lines would be non-existent and it would look fantastic.

Yes, SLA would make it look better but I am not that enthusiastic about the cemicals/liquids needed for SLA.

Black makes the layers more visible and the layers are extra thick to save about an hour on the print time. If I had printed them in white it would have not been that visible.

My personal thoughts on it were to make resin molds to make them little by little.

SMS Shell R2

So I have made a new version of my SMS game shell.

It now uses two countersunk wood screws (3.6x16mm) for putting the two parts together rather than two M3.

I hope to release a version R2.1 that mages the same shell but is better programmed so it uses a config file for easier modification, for example to change screw design etc. but don't hold your breath for that since I am really happy with the current design.

It is still under CC BY-SA 4.0
