If the original handle breaks, you can replace it with this 3D printed element, so you can continue to use it.You also need a 15x145x1.5mm piece of steel plate to make it rigid (you have to push through it).Recommended material is ABS, or other material recommended for mechanical stress, although mine is crappy PLA but it works :-)The inner fill density should be set to at least 50%, and it is recommended to set a low layer count(0,16mm), high quality print.
