Spool rack hanger for wood posts

I've remixed the existing solution for Spool hanger to use it with  cheap wood posts.
wood used is: 60 x 30 mm, Length: 2000 mm (2m).

my setup is to use 3 hanger (one each side and one in the middle)

Printed for extra strengths:

• PETG
• n0,4
• 6 wall loops
• 45% triangle infill

Material required:
 

• 2x wood posts 60 x 30 mm, in your required length
• 2x wood screws per hanger:  3 x 10 mm to fix wood post on hanger
• 2x wall screws per cleat, the screw type would depend on your wall type (wood, concrete, bricks,…)

PS:  this is my first posted project here, so please feel free to post your suggestion or recommendations.
