Enlarged and modified version of @BobMcGlobus_870140 click connector plate for attaching power supply units or power strips to Multiboard with cable ties. (Matching the “Underware” cable management system from HandsOnKatie.)
The original is excellent but has trouble holding larger power bricks.
In addition to this print you will need @HandsOnKatie_827995 's standard underware connector.
The author remixed this model.
Enlarged version for bigger and heavier power supplies. Added second clip attachment point. Requires the standard underware connector (see https://printables.com/model/941161-underware-the-ultimate-cable-management-solution).
I also made the main plate a bit thinner - strong enough but requiring less material.
Prints well without support (0.2mm layer height, 3 perimeters).
Completely remodeled with FreeCad.
