The sincerest form of flattery

People copying my calculators and trying to pass them off as their own is not new to me, but this here kind of is.

I bought a 3D printer about fifteen months ago. The original dream was to get a CNC machine and make some wood mods, but I don’t have a garage or a workshop or anything like that, so I settled for an Ultimaker Original+, a reasonably priced “prosumer class” 3D printer.

I didn’t end up making that many 3D printed mods, because let’s face it, polylactic acid is simply not the most appealing material to make mods from.

But I have designed a few small gadgets from scratch using FreeCAD, for instance this tank tool for wrestling open 22 and 23 mm atomizers that are stuck.


I wasn’t completely satisfied with the design, so later I made an improved version.


So what am I blathering about? Well, today there was a new comment on the page where I had posted the improved version. The comment was brief. In fact it was just a simple link:

Okay. So now some people have decided to monetize the first version of my design. I respect the ambitiousness, and I think their product video is hilarious.

And yes, I am flattered, but I’m also slightly peeved by their failure to respect a simple, agreeable license. The fact that something is on the Internet doesn’t mean that you can do whatever you want with it, guys. You could at least mention where you got the design. It’s not that much to ask.

I assume this was an oversight, so I sent them an email asking them to give credit where credit is due. Who knows, with some luck they might even link back to me.

Hmmm. I wonder if I ask nicely, if they’ll let me be their European distributor? 😉

Then there’s this from China.


It’s prefect for atomizer ciol adjustment.


And that’s all I have to say about that.


I just received a reply from the Attywrench folks. It seems that they are taking the matter seriously. I get the impression that there has been some sort of internal miscommunication somewhere along the line, and that they’ll add the appropriate attribution shortly.

Update 2:

While others were busy copying the design, I spent my time improving it. Then I fired up my 3D printer, and made a bunch. Here is the result.


You can get them here.

Update 3:

If you have a 3D printer, you can download the design for free here and print your own.
