It's a thread of someone's DMR build. He was making it out of foam and I'm pretty sure it was based off of L3X's sliced file. I have been looking for this thread for a month and searching for "dmr sliced foam" isn't much help because dmr is only 3 letters and the search doesn't look for anything below four. If anyone can help me and link me to the thread here, I'd really appreciate it.
