This is a remix of the kiteboard handle by ValkAD. I needed a slightly smaller 17cm handle, so I decided to post his adjusted design with a honeycomb grip if anyone's interested.

I would recommend 100% infill with a 0.4 nozzle set to about 0.2mm layer heights. This is done to maximize the strength of the part. However when using stronger materials one can reduce the infill to something more reasonable.
