🌈Day 9: Hot wire foam cutters. Made these for an upcoming project only using scrap materials, but even if I bought all these materials new it would still cost less than buying an actual foam cutter. I’ll probably look for a better power supply to really make the wire cut like a hot knife through butter (or like a hot wire through foam). Although this project was intentionally scrappy, do you have any ideas as to how I could have done this better? #scrappyengineering #dailyproject #nichrome #foa
