Bow handle fully printable

I wanted to reuse my old bow's legs made by fiberglass but I'm a bit lazy and didn't wanted to work around a piece of wood to make the job.
So, I decided to print it with these settings in Cura :

- infill : 40%
- wall thickness : 2mm
- bottom and top layers : 1mm
- layer height : 0.2mm
- material : black PLA (standard PLA)

After the part was printed, I've sanded down it and then painted. It's very resistant and the bow has been tested OK, no crakkks :-)

My bow is quite powerfu
