Pizza slicer handle (conversion kit)

Conversion kit for annoing type of pizza slicer that has too many parts. (seen in the baground) I made an new simple handle that uses original blade and screw. Also attached files of self made blade that I have not tested yet, plus metal screw is needed in addition. There si also non vut verison of handle attached. I cut mine at the bottom for easier printing with less supports. Original form also attched as stl.
