Power Supply Banana Jack Bracket

prusaprinters

I wanted a more tidy connector for a 12v 30a “universal” power supply.  The little flip-cover over the terminals still seemed too exposed, especially when a few of the terminals are connected to live AC (mains) voltage.  This end-cap box goes over the end of the power supply and adds a mounting plate for a +/- 12v DC output banana jack connector.Hoping the pictures will tell the rest.  If it's something you need, you probably don't need more explanation anyway.The design with the tapered “side box” is meant to print without supports in that area. Adding supports for the screw holes on the sides is probably optional.The OpenSCAD file is included in case you want to make adjustments.The links here will most likely disappear eventually, but for now, here are the parts you'll need. The descriptions might help you search if the links stop working.Power Supply: eTopxizu 12v 30a Dc Universal Regulated Switching Power Supply 360w for CCTV, Computer Project, 3D Printerhttps://www.amazon.com/dp/B00D7CWSCGBanana Jacks: 4MM Copper 2-Way Banana Plug Jack Socket Binding Post Video Speaker Terminal Connectorshttps://www.amazon.com/dp/B09LSTMJJ6Strain Relief:uxcell PG11 Cable Gland 5mm-10mm Wire Hole Waterproof Nylon Joint Adjustable Locknut with Strain Relief Black https://www.amazon.com/dp/B08K8FQ52DMounting Screws:(4) m4x8 (actually just 3 if there's already a screw in one of the positions holding the power supply case together.AC Power Wire/Plug3-Wire Appliance and Power Tool Cord, 3 ft, 16 AWG, 13A/125V AChttps://www.amazon.com/dp/B07BQCMPF2or… easy to harvest from an old computer power cord.Terminal connectors:(7) common “ring” terminal connectors(4) both ends of (+) and (-) wires between power supply terminals and banana jack.(3) on Hot, Neutral, and Ground of AC power wire.
