This product was a waste of time and money. I thought I was stupid > I tried every way I could to get the parts to fit the hand drill. I brought it to my daughter who is a master thinker and foldmaker. She couldn't get them to fit the drill. I was very disappointed as the product is useless. None of the pins will fit the top of the drill that you screw into the drill. You can't squeeze it tight enough to hold the pieces. It is dangerous and potentially projectile. Remove this item from the market. I want my money back and will hopefully never buy from this manufacturer again. BAD, BAD, BAD product.
