3D Printed CT60e Bracket

I've built a power/power button/060 toggle switch bracket for the CT60e, which you can find on Thingiverse or fully editable on Tinkercad.

The text I've written on Thingiverse...

This is a bracket for an Atari Falcon030 computer with the CT60e 68060 accelerator card and a picoPSU power supply. It sits under the CT60e and slots into the PSU slots on the motherboard, and fills the empty IEC inlet and power switch holes on the back on the Falcon case.

In the former IEC inlet space are now holes for the picoPSU +12V input, a CT60e power button, and a 68030/68060 toggle switch. The former power switch space is left available for future expansion.

The +12V input hole (the lowest of the three) should work for any picoPSU (and perhaps for similar tiny ATX power supplies if they use the same size input), but the other two holes may require customisation to fit your own power button and switch. A fully customisable version can be found on Tinkercad.

I found this prints best with the "back" (i.e. the part that shows outside the back of the Falcon once installed) facing down on the build plate. I got best results printing on blue tape with no raft. Since this orientation results in the vertical (post-installation) holes being filled with support material, after pulling the supports out with pliers, I smoothed out the insides with a 7 mm drill bit turned by hand. If these holes aren't fairly clean inside, it will be difficult to get the Falcon top case back on.

Feel free to download, customise, improve, and enjoy!

Nice :). Great seeing all these different designs coming out for the Atari computers.

Yes, good design. I wonder if there is an Atari Grey color?

I ran out of two better colours while iterating on the design. :lol: Ended up with the only non-silly colours left being black and white, and I went with white because it would photograph better.

When I reorder filament, I do plan to see if my local supplier has something closer to the Falcon case colour, but of course since the visible parts are in the back, it's not terribly important.

For anyone who was planning on printing this bracket, note that I have uploaded a slightly improved design. The Thingiverse link in the first post is still correct, but the Tinkercad link for the editable version of the design has changed, and it is now here.

I had my factory PSU back in the Falcon yesterday and I realised that the legs from the Falcon top case rest on top of the feet of the PSU, so my design, which allowed the legs to pass all the way through and rest on the motherboard allowed the case legs to sit 1 mm too low and also missed an opportunity for the legs and the case screw to hold the bracket in place. This is fixed in the new version. This should also improve the bracket's usability for anyone with an older CT60 or CT63, since it no longer relies on the CT60e card to provide any stability for the bracket.
