Reverse CAD Atari ST case.

It would be amazing to be able to buy new cases for the ST. This is an area which is sadly missing for Atari retro users.

Amiga users are very lucky. I have new black replacement cases for my A1200 and A500 and it just completes the refurbishment of our wonderful machines.

IIRC Amiga guys found the original molds.

Yeah sorry I saw the posts on the splits and rejoins also and it’s a technique we use a lot in prototyping but like you say it’s the efforts and accuracy of the rejoin and how you split. Normally I’ll create what’s called an A-surf and split early on in the CAD feature tree.

But in terms of consumer grade finish the surface texture you put on (which is put on the moulding tool) can’t be achieved by FDM/SLS/SLI of any type that technology allows yet. Basically you can’t print a VDI30 surface finish.

BUT if your goal is geometry accuracy and material, finish and colour are not important then prints are fine. I was just looking to the production/commercial route which I’m familiar with.

My gut feel is it’s viable…but to cover the tooling cost at say 500 units you need £30 margin on each case set to break even at the soft tooling costs I believe are in the right ball park.
