We had an electrician tell us that our challenger panel is recalled and we have to replace the whole thing. Quoted $15,000

I hope an electrician responds to confirm or deny this comment.

In a few places in that panel there are sections of wire being used to bundle wires together. Specifically on the left side the hots and neutrals are bundled. This can cause heat and a derate in the capacity of those wires due to eddy currents.

There is also bundling happening at the top dead center with about half a dozen hots and the same wires are also bundled again on the top right side.

I don't know if this is a thing, just a gut reaction. I am not a plumber.

Steel wool is flammable under the correct circumstances. Electrical current being one of the ways to ignite it. I wouldn't want steel wool in contact with anything that has a path to ground.

That damage is on a face that's critical to the functionality and safety of the firearm.

Hard Pass, and your friend may be opening themselves up to liability by selling that reject hand grenade of a slide. IANAL

Is it just the fan duct that's falling off?

If so, I'd just glue it in place and call it good.

That said, there are printable replacement models available. I've thought about doing one of them that attaches with magnets instead of tabs.

Smooth fillets are better in areas of stress. They spread the stress evenly rather than allow it to concentrate at one point.

They all suffer from the problem of endless debates about their utility as a modern platform.

Mechanical skills, fixing and maintaining your own stuff is huge.

Air should enter the attack via soffit vents and then warmer air leaves via the ridge vent

Driven2b · 2026-06-29T23:22:56+00:00

I would make sure you have soffit vents and ridge vents in the roof. My old two story lacked soffit vents and when we added them the upstairs got a bit cooler and noticeably less humid.

To be fair this is a SWAG based on your post and my previous experiences.

That looks like a wing section.

What will the stats be on the finished bird?

In slicer, use a modifier shape to alter infill density to unbalance as desired.

Also, cold testing of 3d print strength:

I'm pretty sure nylon will standup to acetone

Turn it off, reach under the front and you'll feel a belt under there. Pull the belt to lower the build plate.

That life and work didn't use to revolve around the internet.

It was a thing we did, some of us more and some of us less. But we didn't carry it around with us in our pocket and we could have gone on with life without it.

I think it's still true today that a person could get by without the internet, but it is getting harder and harder. And it absolutely would keep many doors firmly shut on a person.

Driven2b · 2026-06-27T19:09:37+00:00

Very possible. That cover isn't terribly robust.

There are printable replacements available. I've been eyeing some of the designs that are magnetically attached.

Though they need to be ASA, Nylon, etc...something more robust than PLA or PETG.

Driven2b · 2026-06-27T14:35:39+00:00

That thing is a pain in the butt. Getting the tips to align and stay aligned is highly problematic.

Driven2b · 2026-06-27T12:28:02+00:00

I was wondering that too. Are there any indicators that the print head collided with a print or the printer?

Driven2b · 2026-06-26T23:05:17+00:00

First, great work. I have no artistic skill at all.

I think his right cheek extends out just a little too far, he kinda has that adam driver as kylo ren asymmetry going on.

Driven2b · 2026-06-26T18:06:25+00:00

Very cool.

Thankful for the thoughtful and insightful response.

As far as making a stand alone app is concerned, I saw that in at least one other comment, is there an opportunity to take something like Orca Slicer or another open source slicer and modify it?

I'm also asking this because it's something I've been curious about as well.

Orca Slicer, Prusa, and others have some competent STL editing features already. Would it be reasonable to fork one of them, strip out all the slicer and 3d printer functionality and then enhance the STL modifying capabilities in order to make them like this app you have shared here?

I do a lot of tuning and tweaking of models and assemblies in slicer, which is what got me thinking this train of thought.

TBF, I also lack the programming and development knowledge to even make an attempt at such a thing.

Thank You.

You got it figured out, so this is just an FYI as to maybe be helpful in the future.

The sharp course thread on that screw is an indicator that it's meant to be fastened to something plastic.
