zx80 powersupply 3d case anyone ??

[jojo]

Anyone ever made an stl file ( 2 ) for the original zx80 power supply ??

all info is helpfull

Wasn't the original just a large moulded plug with all the electronics in it rather than a separate unit as we got for the Spectrum. Only saying that as you may struggle to 3D print a replacement that houses it all, well as easily as the box is to print anyway.

The zx80 original UK version was a rather bulgy box with the contacts embedded in the plastic .

i would like to recreate the white version ( but don't have any 3d experience , except for using the prints ).

you use paint to make an excisting black one WHITE ........................

but i need a black one first .

Why do you need the print? Is it to repair a broken PSU and you have the original transformer and PCB? or will you use a modern PSU circuit inside?

I ask because looking at the original PSU, it would be hard to 3d-print the earth pin in a way that would guarantee it would not snap off in the socket. Other than that, the shape of the case could be recreated if the dimensions can be given.

As i am not a 3d guru i asked the specialists in this forum first .

and indeed i want to recreate it to accompany my zx80 clone

Design it to accept a separate earth pin that pushes through like standard plugs?

I think that would be the best way. I was interested to know what 'innards' [mention]jojo[/mention] was going to use, It may be that the original had an inserted earth pin already. It may be that on the original, the plug part is on a separate moulding that could be used with a 3d-printed shell. If it is being built from scratch you could use a brass pin out of a regular plug, although a solid plastic pin would be better considering the earth is not connected. It is quite possible a suitable pin could be scavenged from a phone charger or other wall wart.

Does anyone have a zx80 PSU and can measure the case? If a case is out there, i can draw up the shape and post the drawing, and the dimensions can be added.
