Parkside Paintholders Vallejo

I imported a Parkside box , then boolean modify everything but the connectors for the wallmount and some small ‘’bar'' . Downloaded the skadis paintholder . Imported it in blender , Booleaned the skadis connectors so it would be blank . Then unified the parkside slots on the paintholders . I added the file in blender . this is my first upload … so if anything is wrong , all help is appriciated p.s sorry for my bad typing
