10A PS upgrade for MPMD

thingiverse

I created this to utilize a 10A power supply with my MPMD machine. My goal was to craft something that would seamlessly integrate with the compactness of the machine while allowing me to include a mains power switch as well as a couple of extra switches for 12v accessories such as LED lighting. It includes top and bottom parts for the PS which hold the switches in place. These components are precision-engineered to fit snugly around the switches, ensuring that electrical connections remain secure and not exposed or against the metal column. I also designed a clip holder that snaps into the aluminum frame extrusions, securely attaching the PS to the printer without requiring any drilling. This setup also holds the backing plates in place since they are not designed to fasten together; instead, they rely on press fits. If desired, you could use glue to secure them. To assemble this project, you will need a 10A power supply of the same size, a mains switch, and two push-button 12V switches. I also added a 90-degree plug to maintain the original delivery of power to the machine without any modifications. You will require the following items: 1 - AC 110V - 220V to DC 12V 10A (47mm x 34mm x 187mm) 1 - 10A 250V Inlet Module Plug Rocker Switch Male Power Socket 3 Pin IEC320 C14 switch + Fuse 2 - 19mm 12V (LED) Latching Push Button Switch 1 - male 5.5x2.5 mm Connector Cable Plug Jack Adapter (DC Pigtail Male 90 Degree Wire 5.5x2.5mm) I added two switched lines for auxiliary lighting, which can be customized to fit your specific needs. To ensure flexibility and ease of maintenance, I chose not to wire directly to the board. Instead, I used a 90-degree pigtail to take the main power to the standard PS jack, allowing me to easily remove or replace the power supply if needed. I could have added an additional switch for this purpose but decided to use the main power switch to control the printer's on/off function. During design and construction, I considered adding a power connector for my Raspberry PI but ultimately decided against it, opting to keep the two devices on separate power sources. This leaves room for potential future modifications or upgrades. Note: I designed and built this project approximately a year ago in response to a request. Although I believe the STLs are correct, there is always a possibility of errors. If you notice any issues with them, please let me know so that I can address and resolve the problems.
