crate low poly (had issues with high poly)

after attempting to create a high poly crate i gave up after having many failed attempts and errors. so i decided to make a simple one instead.

i followed the tutorial on how to start the crate to make the handle after getting my first error i decided to duplicate the shape that had been made instead of using the mirror tool.
i then joined them together using the combine tool and started to make the side panels. i used a cube and re scaled it to how i needed. i then duplicated the ne i made to get the right amount of panels.
Once i had combined them together i then created the four sides that i needed to create a completed crate. i then made the bottom.
this is the completed crate once the bottom was made. i know it isn’t great but i had a lot of problems/errors while attempting this but i hope to make a better one in the future etc.
