I modified the closet to be a changing room in our bedroom. This model includes the files for the closet brackets to work with standard 1" dowel rods from the home center. Intended use is for baby clothes, so I only mounted these with drywall screws. 

If you expect for these to bear more weight, screw into a stud with a construction screw, or use drywall anchors with matching Flat Head Cap Screw hardware

PETG is the tested material - it was in use for over 2 years with no issues.

STEP files include if you need to modify for different hardware or dowel sizes
