I doubt anyone on this site will have a use for this, but I figured I'd upload in the off chance that one person could benefit.

Background: I had an ancient bathroom fan go out on me. The motor was shot completely, so I bought a "universal" replacement. Unfortunately, it wasn't as universal as I'd thought and did not fit the bracket provided with my old motor. I couldn't find any bracket that'd fit the thing online, so I improvised.

So, me, completely unskilled, brought the thing into Tinkercad, measured all of the holes, and designed then printed this.

Of course, print at your own risk - I printed in PETG and it's supporting the motor and the cover plate just fine, but who knows if it'll work for heavier motors. If you're unsure, maybe stretch the

For reference, this is the universal motor I bought. There are a variety of them available online, and I suspect anything that looks vaguely similar should fit this bracket. Double-check the measurements of the holes before printing, just in case.

Notes:

I used tree supports in Cura and it worked wonderfully. They were easy to remove and didn't screw with the holes. Took about two hours to print with my given settings.

You might want rafts, since the contact surface isn't huge, but I printed four times on a heated glass plate with hairspray with no issues.

PETG or above is probably the best, considering it's likely gonna be supporting the weight of the motor and the cover plate, but my prototype was printed in PLA and seemed ok for the hour or so it was fastened.

Post-Printing

You may or may not have to clip off a corner with some wire snips or something - one of the square corners butted up against the corner of my fan housing - you can see in the photo how I clipped it to have it fit. It's easy enough.

How I Designed This

I stumbled my way through Tinkercad until everything looked ok.
