And if you insist on being unattractive, then have you tried being rich?

Yep. When buying a product, it ain't about the packaging, color of the paint, or the sticker/badge hung on it. It's all about the service when things go sideways. And at some point something will go wrong, it always does. That's when you learn just how good or bad a company is.

As a boomer, reading this thread/discussion has been so amusing in many ways while enjoying my cuppa tea this morning. A classic "the younger generations are stupid."

The older generations looking down the ones that follow. And the following generations looking down on those that precede them. And no one understanding ain't none of us are all that bright.

Ever has it been, and so ever shall it be.

And there is little reason to do input shaping on the start of every print unless you change the mass of the moving parts by a noticeable amount. And even then, it does nothing once the print starts. You get what you get anyway when the print is finished.

What would be better is if a printer could measure and adapt to the changing resonances as the printer was printing. But I suspect that ain't going to happen anytime soon due the complexity and the ultimate question: "How good does good enough really need to be."

Only if the lock isn't worn or dirty on the inside. I wouldn't trust this for any outdoor lock or older lock. Even cheap locks with poor fit and finish causing rough operation would not be a good idea. This is a fun gimmick that could easily cost you more money than it's worth.

The only way I might use it is if I were to use the 3D printed key as a pattern to cast a metal one. And I ain't got time for that.

It should work fine enough for what it is and how much it might actually get used.

Being plastic, the squirrel cage blades are very light, but balance could be an issue, because of the unsupported end and depending on how fast it spins. As a desk fan, this one should not spin very fast or move a lot of air anyway lest it blows all your papers to the four corners of the earth. If you want to move more air, you need a different style of fan.

Getting a good fit, (Ender 3 or not), is a matter of tuning your printer, print orientation, and some test prints to check whatever windage you need to apply to get the fit you want. Post processing, like using a drill to ream out the hole for size and roundness is often needed to achieve that goal.

Over all, I think it's an OK design that will do what it says.

It ain't about symmetry or pointless complications. It's about how many numbers can you get on a watch face and have it be easily legible. Yes, I know there are digital watches these days. But some people don't like them and some of us need those analog faces. As an old medic, digital watches absolutely suck at timing things like BP or respiration's. Neither me or my patient had time for that digital watch to zero so I could get a BP in 15 seconds. Ten's of thousands of EMS people and nurses in general are wearing 12 our analog watches around the world right now.

Now my run reports were all done n 24 hour time because the little boxes on those paper run reports were tiny and often filled out in a hurry. So 24 hour time was more legible and clear to anyone reading the report.

Besides, can you not look out a window to see if the sun is up or not? That will tell you all you need to know to understand how to use 12 hour time.

FreeCAD or I will go back to my pencil, tee square and compass!

I have used AutoDesk products, (anyone remember starting AutoCad at a DOS prompt? I do), and Solid Works professionally. I have tried Fusion, OnShape, (taught a class to senior high school students for a few years), Solid Edge, and a host of lessor open source projects. All of them suck in some fashion. They are all waiting to trash your 100 hours of design sweat, (I got all the tee shirts). And if that's the case, I'm not paying $50US a year for SW. I will wear the sackcloth and ashes of FreeCAD instead. At least it didn't cost me anything to lose my work.....

5 years of on and off trying and I still can't make the doughnut in blender...........

It might have been an extra reason.

Well, it's still a far plan than the time the French tried to force time into base 10......

Which might have been the first documented demonstration of the saying "The French follow no one. And no one follows the French."

Machines are still cheaper. They don't need to be fed or housed every day and you get more work out of machine per hour than any living creature-- be it a horse or slave. And when you are done with a piece of equipment, you turn it off and walk away.
