QiYi SQ2 (help needed!)

[YouCubing]

So I recently got a QiYi SQ1 to mod into a QiYi SQ2. I'll explain how I'm doing that now and why I need help.
1. Remove all the corners and edges.
2. Cut the corners in half so that they become SQ2 corners.
3. Reassemble it.
Pretty straight forward. So I need help with step 2. I need to know how to cut the corners. I think there are knives you can use for plastic cutting, but I don't know where to find any. I've been told to use a dremel, but I don't see how that would work on such small plastic. I've disassembled one of the corners into the 3 pieces, but I still need to cut the piece with the top sticker in half.I made a thing to help visualize what I'm talking about.
So basically, how can I cut plastic cleanly?

Why wouldn't you just get 2 squans and use all the small edges on one cube?

this, though you'd need to make pointed extensions to the small edges you use

I thought of that, but I got white squans for some reason and couldn't find any white epoxy. Plus, one of them is my main now

He'd need three.

Something like this is likely the best option

Epoxy color doesn't matter as long as you have white spray paint.

The Calvins Square 2 isn't too bad, I finished restickering mine yesterday. You'll have to be very careful cutting!
