I added another version today that has a 2mm ring without the chamfer, btw.

They sit 3mm proud. This is not an issue if they are hidden, me thinks. However, you should be able to not use the support ring if it is an issue. (I’ll modify a design today in attempt to reduce the amount it sticks out.)

Also, these are intended to be extremely secure and almost permanent. If you want it flush, you can probably pound it in a little more with a hammer. If not, leave it proud and it gives you a little meat to pull it out of the wall later.

Thank you.

Isn’t it really cool that some of the best engineering projects leverage extreme simplicity? I am not saying that I am a grand architect or anything like that, but this simple project is a perfect example of why most people want to learn 3D printing.

After thousands of dollars were spent on 3D printers, rolls of filament and replacement parts with hundreds of hours dedicated to learn about printers and CAD, it all just boiled down to being able to design and print a silly drywall anchor on a whim.

Ain’t this hobby glorious? :)

Aww, thank you! I can be a sarcastic ass sometimes, but such is life. Regardless, it’s fun to design and share things. That reminds me… I included the .f3d file with this design but I forgot to add a .step. I’ll add that and some clearer dimensions for it tomorrow.

Lemmy just needs all the love it can get and interactions are super critical for that. After being on Reddit for over 12 years, it’s great to be part of something new.

Thanks for comment!

I tried a few anchors that were already out there all of them broke at the layer lines easily with PLA. Granted PETG would probably have mitigated that issue, but I didn’t want to change filaments.

The toggle anchor would be fun to design, but designing a hinge that would work universally across many printers and filaments would be a challenge, for sure. Cheers!

It can, yes. However, it is only by 3mm. The print orientation is the way it is so that it can survive a hammer and some love taps. (I already tested that, btw.) Additionally, I wanted some extra meat on it for easy removal later and it may be hidden, depending on your application.

In theory, you don’t need the support ring if the hole you drill in your drywall is a perfect fit. I have traditionally drilled my drywall holes a hair small for these kinds of mounts, so if you do that, not using the ring may work. Or not.

It linked just fine! I think I can post to kbin via lemmy. Not sure…

Eeeeyyy! I just found the stud.

You can yell at me all you want! If you need a hug, I can get you one of those as well, no charge.

I am using some of the mounts now for some pictures, but I can say they are extremely stout, at least the way I printed them. You have to use a hammer to tap them in the last little bit so it doesn’t spin. They survived some fairly hard love taps, and once the screw was in, they aren’t moving.

Your personal experience may be different.

Oh awesome! I just saw this design on Printables today and really wanted to see it in action before I committed to the print. Thanks for posting.

Are there any print or build issues that I need to take note of, or is it as good of a design as it looks like?

They expand quite a bit and the little tabs are intended to dig into the drywall to keep the assembly from rotating while it the screw is set.

I suppose you could cut the little tabs off and not use the ring and it would still work. It may be problematic since the main anchor bit is split in half.

Cool, I’ll add better details, for sure!

Fyi, it should work for screws with a diameter of ~3.5mm. As long as you can get the screw to self tap its own threads, you should be OK.

Everything should be a very tight fit, when all is said and done. I have to press the anchor bits into the cap by pressing the assembly together hard on my desk.

You’re welcome! I was too lazy to run to the store. ;)

It’s probably limited to the thickness of the drywall. All I needed was a lightweight shelf and maybe a picture or two. I would have to test it to get some real numbers.

Köttbullarna kommer att följa!
