Need some help with model convert from Effect to prop

[GarryLT]

I had looked around here about prop converting from effect (props which has green ring on it) to solid prop. I couldn't find proper tutorial or ways how to do it. Maybe someone could give some instructions or willing to help me.

So I have ripped two models which i want to convert to props:

1) Multimeter as tool for defusing from CS:GO
2) Accordion from "Serbia - kebab remover"

I tried the help from this post:" effects into props? "
But crowbar software drops me an error.

What defines a prop is the $collisionmodel and, fun fact, what defines a ragdoll is the use of $collisionjoints instead of the aforementioned one.
Here is what a very basic prop QC looks like:

$ModelName "knife\knife.mdl"

$Body "knife.smd"

$SurfaceProp "plastic"

$CDMaterials "knife\"

$Sequence "idle" {"anims\idle.smd"}

$CollisionModel "knife_physics.smd"
{
$rootbone "knife "
$concave
}
That is one of the first QCs I've ever made so, I had to delete a lot of useless stuff to make it even more basic so it might not even work, but it should.
Now, the collisionmodel itself is the hardest part, it needs to be made in a very specific way for it to work, and you need to do it yourself since the models don't have one.

Luckly for you, I have just the thread for this kind of problem, I keep throwing around this thread but really it's because I put so much effort into it:
Just ported a model but 2 issues occured
In the thread I also made a collision mesh for the lad, so making it for you is not out of the question since it looks like they might just be squares, but the thread does contain enough info to do them yourself.

Thanks for showing the solution, ill try to make it by yours provided information. Well for just in case, maybe someone knows where i could get similar prop addons. I know i can get accordion from:

But i don't know where to get the "Multimeter" addon. If someone know, would be nice to know

@Grodbert thanks for linking to that thread, but also my one Gmod fella showed one tutorial ,link here:

So it helped a lot, even skiping some steps, seems you can make collision mesh like prop form in seconds, well now i am very happy to know more about stuff, and some additional knowledge to server developing.

It's also important to note that by using that guide you will only use convex collisions, this is good for small objects but if you want to make a better collision mesh remember to add $concave in the collisionmodel, the collision mesh itself will need to be made out of multiple convex shapes.
