This is a simple DPS5005 case. It prints in 4 parts and uses M3 square nuts to fasten the case.

You will need:

• DPS5005 module
• Some wire (I use AWG16 silicone wire)
• DC 5.5 * 2.5 MM Power Socket (https://www.aliexpress.com/item/20PCS-DC-022B-DC-power-socket-DC002B-5-5-2-5-MM-sockets-connector-with-nuts/32759269622.html)
• Pair of banana plugs (https://www.aliexpress.com/item/2pairs-black-red-Splice-Terminals-4MM-BANANA-PLUG-POSTING-AMPLIFIER-SPEAKER-TERMINAL-AUDIO-JACK-GUNUNG-BINDING/32323282810.html)
• M3 ISO4762 screws (M3x15 should work fine)
• M3 suqare nuts (DIN562)
