Well, This idea is not the best but If I share it to this community, Will it be the best? Idk xd.

So, this is how the idea is.
You make a 3d item[s]
Then you make a thread in here
https://gyazo.com/ae5bc7ee2870cb80db1f73eee31b6669
And say that you made that item, Tell the desc for it.
So, the Item Forgers will see if its good item or not. If its good, It will be added into the Torishop. If it's not, It will not be added.

Please tell me if it's good ;-;

We currently got 1 thread for suggesting items. I don't think a whole board would be needed for this. http://forum.toribash.com/showthread.php?t=397629
Only difference between this and what you're suggesting is that we should make the items ourselves, but if you'd like to do that to give a better example, you can do it in the thread too.

Oh, my bad. But you can make 1 new thread for Item Showcase right? Cuz I have my own 3d items ;-;

a subforum of the art thread could be useful for this, have people's custom 3d objects they use and get cnc or just share their creations

That works too.
