Dual Bench Power Supply

There's a whole bunch of existing models that will house a cheap panel-mount DC regulator for the purposes of creating a bench power supply.  But I wanted one that would provide two different voltages.  And would have some USB ports  And would get its power from a lenovo laptop power brick.  And wouldn't require butchering the power brick, because I need it for other stuff.  I modeled this from scratch in tinkercad, because I'm a hack.

Here's the parts I used.

Want to use a different type of power brick?  I intentionally made the cable bracket a separate piece, so you just need to modify that to work with whatever type of power inlet you wish.  I didn't bother including a fan grille - there are plenty of printable 40mm fan protectors out there.

Use M4 bolts for the fan, and M3 hardware for everything else.  You'll also need a zip tie to hold the USB board in place.

Print all parts as provided.  Supports are recommended for the front plate, but not strictly necessary if you have your bridging dialed in.  Nothing else needs supports.  ABS or some other high temp material is recommended if you're going to be running these for extended periods with high loads.
