100W Boost Supply Case

thingiverse

This is a case for a 100W boost power supply easily found on eBay. The supply lacks a part number, but it's listed as "DC-DC 100W 3-35V 12V to 3.5-35V Boost Step-up Module Power Supply LED Voltmeter". I purchased from seller zjpower18. The case includes some extra space around the PCB, standoff pads, and posts that can be re-melted to securely attach the supply in the case permanently. The lid has a viewing hole for the display and a button that switches the display between input and output voltage. Pressing the button might require some manual trimming after printing to get it to fit properly and work well. Four small screws are required to mount the lid to the case. A version with external screw mount tabs was added on 4/24/2019. I placed the tabs near the wire access since this keeps the case as narrow as possible, and wires must enter or exit in that area anyway.
