Design project

Need 3d cad design for small box (4x5 x 4 inches) with integrated slot in back where a steel bar support stand will be inserted. The metal bar will be 1/16 inch thick and 1.5 inches wide. The support bar will insert vertically into the back of the box and then extend downward and do a 90 degree bend to insert horizontally into support base. A tension screw should be designed integral with the box and stand to apply tension to the insert bar to keep it secured.  The box will be suspended over the support base. The box will additionally have an approximately 1/2 inch long x1.5 inch diameter integral male threaded cylinder to accept a threaded cap. The cylinder will be centered in the back of the box.
