I can't get the corner parts to work. i is sad.
Make them. Attach them. Forcefully if you have to. But goddammit don't make another WCC thread. newfags these days.
In the process of making mine.It are not easy...
i used double sided sticky tape for the tabs on the corners of mine. its a bastard to stick down, and i couldn't do the little edge bits coz its on a4 paper and i have shaky hands..
