New Power Supply for (Home) Electric Lock System

For over a decade, my (self-installed) electric lock system from the garage to the utility room has been running on a used PC power supply. The cooling fan had stopped turning, the power supply was discarded, I peeled up the foil sticker over the bearing and added oil, and the fan worked again for another five years until its next service appointment.

This fall, the power supply stopped altogether; and that became the impetus to install a smaller, silent (passively-cooled), non-PC power supply.

    Wow, very cool! Great to see a MakerBot in service for practical applications like this!

    Bre, I totally agree — I have lots of practical little applications in store, and I’m pretty excited about it.

    I haven’t Thingiversed this one because it feels pretty specific to the dimensions of my power supply; and since I drew it in CATIA other folks would have to import the STL and modify that in order to adapt it to their own needs. But I will be Thingiversing future models, never fear.
