Closet Retainer for Clothes Rod (Universal)

I designed this for my wife – we had a loose clothes rod in one of our closets, and it continually was popping out of the top of the holder. I wanted to design a “clip” to help keep it in place, as well as to be able to take up some “slack” because the previous owners had cut the clothes rod too short. 

I designed this clip to be adjustable to allow for customization to any similar clothes rod, and the entire model is “parameter driven” in FreeCAD (so no CAD programming is required--just type in the measurements for your situation).

I've included the reference FreeCAD models that are completely parameter driven. If you'd like to customize these models for your own situation:

• Download FreeCAD (https://www.freecad.org/) and install it on your computer.
• Download my .FCStd file from MakerWorld and open it in FreeCAD.
• Click once on the “{VarSet}” line (on the left side in FreeCAD), and then adjust the parameters underneath for your specific vice requirements. Note you can rotate by clicking on the “cube” in the top right to see your changes.
• Then choose “File…Export” and choose “STL" (or “STEP” if you prefer)
• Go into Bambu Studio and select “File…New Project”
• Then select “File…Import” and adjust the position on the build plate if needed, then slice and print as normal. (Default Bambu settings should be fine).

Some features (and parameters) you'll want to consider setting and/or adjusting:

IMPORTANT - none of the variables can be set to zero (but they can be set to a very small number, such as 0.1 mm)

• Bottom_Thickness - this is the thickness needed to make up for a clothes rod that was cut too short. 
• Clearance - this gives some necessary clearances throughout the model in some key areas. 0.25 mm is probably sufficient and it'll be unlikely that you'll need to change this. 
• Clip_Height - this should be set to the height (length really) of the rod holder you have in the closet.
• Opening - this is the “missing part” of the circle on the rod holder. Measure this from the holder in your closet and enter the value in mm.
• Radius_Inner - this is the inner radius of the holder in your closet. You may want to print a set of radius gauges to help determine this parameter.
• Radius_Outer - similarly, this is the outer radius of the holder in your closet. Again a set of radius gauges will help.
• Wall Thickness - this is the thickness of the walls of the “clip” – you can likely leave this set at 3 mm.

If you're unclear about which parameters affect which parts of the model, make a small change and see which part of the model changes. You may want to print one of these “as is” and then compare it to the rod holder you have in your closet, and then make any needed adjustments accordingly.

I'd welcome comments and suggestions, and I hope you find this print useful.
