Table Tennis bat with laser cut files

Hey, this is a table tennis bat that i designed on Onshape, it currently does not have a print profile but all of the STL files can be found on this page, i have also included a laser cut profile (DXF) for the blade which is what is shown on the front cover. This is my first model of this kind so any feedback, good or negative would be deeply appreciated.
