X-acto knife for #11 blade

This is an X-Acto knife designed for an 8mm wide blade (#11). There are two options for the handle: one knurled and one without. I gave you this choice because it's my first knurled design and I am not convinced it's perfect to print. If you have any tips to improve my design please contact me.

Take the updated handle for better knurled design.

If you want any sorts of CAD design, I am willing to do it.
