LM2596HV Buck Converter Mount

thingiverse

My first ever Thing on this platform, and also my very first model created in FreeCAD; your mileage may vary. The LM2596HV (or is it now the LM2596HVS?) is a DC-DC step-down converter, similar to its plain counterpart, but with one key difference - it has a USB socket and requires no adjustment to output 5V directly. This model was specifically designed for my Raspberry Pi, which I have running OctoPrint attached to my trusty Ender 3 Pro. For those interested in remixing this design, the FreeCAD model is included. **Additional hardware needed** To mount the board securely within the enclosure, I used tiny screws - specifically M2 or M2.5 (I'm not entirely sure which). Rest assured that the hole sizing will depend heavily on your printer's calibration. The case itself features pre-drilled holes for M4 bolts, which I utilized to attach it to my printer's extrusions. **Slicer notes** To ensure the screw mounts are sturdy and reliable, I printed this model at 100% infill. However, you may be able to get away with a lower infill percentage if you prefer.
