As chintzy and cheap as that foam already looks, there's gotta be a better way to figure out how to remove blocks without leaving marker lines on it. Thanks for bringing this video to us- good to help plan ahead for a project like this.
There are better ways, such as using toothpicks to line the outlines or just score the foam around the outline of the firearm. Also using a hot wire tool, which I don't own, cuts the foam much cleaner. Trial and error, but the price is on point!!
