This is a set of models to help with your cable management.
These are desk or table hugger clips.
Clips were initially made for Ikea linnmon tabletop but are fully compatible with lagkapten and målvakt tabletops and any other tabletop or desk that's 34mm (1 3/8") thick.
If you have a specific thickness you would like to see added leave a comment!
One model has one closed-when-mounted ring while the other model has an additional partially open ring for easy on the fly adding or removing of cables.
Both models are available 20mm wide (pictured) and 30mm wide but other widths can easily be made by resizing in your slicer.
FreeCAD 0.19 parametric model is also available for your editing pleasure.
