Mini Bench PSU

thingiverse

This is a custom-built workbench case for a few components I assembled to create a mini bench power supply. The project utilizes a widely available 8A buck-boost module, which can be easily sourced online. I relocated the onboard multi-turn trim pots to the front panel of the case using spindle screw extenders that were carefully secured with glue. These extenders provide extra stability and support for the trim pots. The parts were printed flat on the bed, and then assembled by gluing the front, back, and bottom components together. Next, I glued the sides and top pieces in place. The resulting design features a double U box configuration with rebate joints for added structural integrity. I successfully printed the case using PLA material at 100% infill and a 0.3mm layer height on my Ender 3 without encountering any issues. To secure the XT60 input and output connectors, I used short M3 screws and nuts.
