This is a modified variant of the handle from Kriby Downey's outstanding Thorn Hand Cannon model, from the game Destiny. I had difficulties printing the handle due to the complex geometry and overhangs. Supports simply did not do the trick, so I divide the handle along the long axis, enabling it to be printed in halves. They jigsaw into the rest of the model as intended after the halves are glued together. I expect this change helps people who are having the same trouble that I did!
