How to make hollow corner wedge?

Hey guys! Today, I’m going to make a hollow corner wedge (for tender as an example of an image), using a union, but it’s unfortunately been glitched. This is due to a Z-fighting. Look for an example of an image:

Now, I’m using this method. I’ve tried the plugin called “GapFill”, but it doesn’t the same size. But watch the second example of an image:

In the third method, I tried to use a part called “CornerWedge”, but it doesn’t align either.

In the image below, so how do I make a hollow corner wedge?

Just tried to replicate your issue with gapfill.

I’m assuming by the size not being the same, you meant the fill part is too large. But I selected “Plate” and got a part that looks roughly the same thickness as the 2 parts your trying to connect.

I’m pretty sure that’s not Z-fighting, correct me if I’m wrong! in my oppinion, I hate union

You should be able to achieve this shape through unions and negating.

Continue on with shaping it out with negates, and then just import the final union into blender and delete the unnecesary faces.

No, it’s correct, this is my solution for this method. Now, we use the CornerWedge part to fit between 2 parts. This is my example of this image:

I’ve looked for it, and you have replied to me, so I solved it myself. Now, thanks!
