Parametric Aquarium Cord Keeper (REV 2)

If you have an aquarium then you understand the struggle to manage and bend cords.  This print safely routes wires over the top of the tank with a visually pleasing, smooth bend.  

Revision 2

Revision 2 adds cord keepers with different angles: a horizontal, 90-degree version, and a custom angle version.  The designs conform to the same A and B style constraints.  I also added a variable to control the minimum wall thickness where the inner-bend and glass come together.

3D Design

The design file generates two models: 

• Model A prioritizes a compact size at the expense of bend radius.
• Model B prioritizes the bend radius at the expense of overall size.

For some combination of values the difference between the two models may be hard to see.  The difference becomes noticeable when you use thin glass and/or a wide bend.  Below is an example of how the overall size and bend radius can differ:

If you are concerned about aesthetics first then use model A.  If you are concerned about the minimum bend radius to prevent cord damage then use Model B.  

Customization & Variables

There will be a large variety in cord and rim size.  Thus, I include an f360 parametric design file.  Take measurements with calipers for the best results.  Here are the customizable dimensions and associated user variables:

Thanks for visiting, and enjoy!

Major update: Added two new versions for revision 2.  Thanks to https://www.printables.com/@Pozwerty_2313093 for the idea.  I added small fillets to edges to help with printability.  I also added thin_wall to the list of user parameters.
