About this 3D model

Made a simple display stand for the HC Diana foam dart blaster using negative parts in the slicer. Because of that, there was some warning stating “conflicting gcode detected” but it's as intended. Would greatly appreciate it if anyone could make a proper STL/3MF and print the profile from the raw file. Update 8/12/23 : Fixed the file by using the slicer's “assemble” function, warning has been removed. Should print with no issue but let me know in the comments/review!
