Travel friendly Citadel Paint Stand and Box
Modified design to make it more travel friendly. On the lid I added holes for threaded inserts to attach a handle, I used M6 threads and bolts. Changed the design to add threaded holes to the stand portion with matching holes on the lid so I can use locking bolts to hold the lid on when I pick it up and carry it around.

There are two plates for the bolts, you only need one. I used the horizontal ones for added strength. The other plate is for printing vertically if you'd like to print that way. Although they wont be a strong,

Handle I used was from https://makerworld.com/en/models/65461#profileId-68829.
