Did you attach the STL? I looked at your post but couldn't see it.

Ooops. I did attach the stl and step file but looks like the forum doesn't like those and just removes the. I zipped them instead now and attached it to the previous post.

I have a couple of machines that I bought with the power button missing altogether, so I needed a complete reproduction rather than just a repair. I wasn't particularly happy with the shape of the button part in the thingiverse STL, so I've made my own. It still needs a few tweaks, but it's coming along nicely.

And yes, I know it's the wrong colour.

I've refined the button design a little, and I'm finally happy with it. I printed it with a 0.16mm layer height.

It should fit onto the base part of the original Thingiverse file, nice and snug.

STL file attached if anyone wants it.

Is it just me or does the button always tend to want to go to the left?

Here's the STEP and STL files to add the clips back to an original button. I'm tempted to make an extension of the original button to make it so it won't need to be pressed so much and get stuck sometimes like the original.

Kudos! The originals were nice until time's tide came along. They are incredible brittle now those buttons are. So yeah, good job!

There's a lot of play in the position of the top case.

@Branchus can I ask what software you used to build this STL - I'm new to this and trying to figure out what the best tools are! I'm planning to build the motherboard standoff clips and the internal power switch clip (all of which are broken on mine) as an STL and share them here in case anyone else needs them!

First test printed. It seems pretty robust, so I'm pleased. I may make a few revisions though. I'll use the original button bit so that it looks original.

I just did a 3D print from a STL file at https://www.printables.com/model/941283-apple-power-macintosh-7xxx-power-switch using a PRUSA printer and PETG material. I am not impressed. Perhaps I need to use a different filament material.

This switch look better.

That model looks like it's a 3D scan rather than something that's been parametrically modelled. It looks pretty rough to me.

The file is from printable.com. The PRUSA slicer must need some tweaks.
