Simple cube model request

I'm making a Snake map for Wc3. For the snake body segments, I would like a simple cube model because (I assume) it doesn't take much graphics power (since you can have hundreds of segments). I originally had wisps for the segments, but the frame rate drops to 30 after there's more than 100. I have zero modeling experience so I don't know how reasonable of a request this is. It would be nice if the cube changes colors depending on its owner, but that isn't necessary. Thank you for your time.

It is not about graphics, its unit data that lags. Changing stuff to cubest wont help, since I am sure that wisp's polycount is lower.

I'm pretty sure the model counts, because when I change the model to blank the framerate stays the same. And I don't know much about graphics, but I'm pretty sure a wisp model has more points than an 8 point cube. Regardless, I would still like a cube model since I have other ideas.

here it is, nonetheless. it took a whole 5 seconds so don't need to hanks or give credit or anything (no, really).

yeah
a cube is literally click, click, click-hold,release, export, done.

actually it's more like "box()" and that's it.
