Jeep Cherokee XJ manual window crank knob

I have a 93 jeep cherokee and my manual window crank knob kept breaking, so i made a version of it and printed it out. i ran this at 25% infill and it seems to be holding up pretty well. I didn't put the hole or the x slot in because it makes it too weak and breaks right away. This one is solid and with a bit of force it goes right through and locks in place. I have to convert to mm in Simplify 3D and the overall height on Z is 27.94mm and X and Y are 26.66mm.

Update: I forgot about the scali
