This is a remix of the middle finger gravity knife. I made the original one for myself and soon had to make one for my wife and then more for friends. My wife wanted a less offensive one she could use for older members of our family. So I decided to change the blade shape to a heart instead. That of course also required a change to the outer handle to no longer say FU.
Print with PLA, 15% infill is sufficient. I used organic supports for the handle pieces, but it should work fine without any supports as well.
