Hi, my name is Daniel and I like to make stuff. My journey on Youtube began with creating things around the home with my 3D printer. I'm mainly focused on making functional items because I am relatively cheap and don't like to buy overpriced goods. Also, making my own things means that I can customize the item to my specific need. I hope that my channel inspires you to Just Make It!
