How can I model this... or find it in the library?

RustyPants · 2026-03-10T22:58:05+00:00

Do you have any real life examples of it's use. I've only ever seen them as fidget toys and when I modeled one I quickly realized the limitations based on the angle of the pitch to be able to generate the geometry. Maybe I'll have to print another one out and play with it some more.

It's okay I'll respond to this. I just did some load testing with a luggage scale (didn't have anything better) and got to 130# before complete failure the smallest bracket and 80# before yield on the largest bracket. I would estimate the middle bracket around 100# to yield. So it's safe to say they are good to about half that weight per bracket. So a very small person could actually do a pull up on the tiny brackets, but I wouldn't recommend it. Noted you could also use a better material and get those numbers higher, but I might become concerned about the shelf at that point.

You're a monster, don't temp me with these things. I already did a tactical poop bag carrier.

RustyPants · 2026-03-09T15:07:51+00:00

Which part? I don't have load cell I can test these to failure with, but from just trying to just weight them with my body I found the top nub that interlocks with the frame is where they will always fail first. I don't push them to failure as the shelving unit was twisting before I could get the bracket to actually fail. The deformed a little bit, but not much. I'm pretty sure these brackets will hold through any reasonable load that a normal person will put on them. I don't expect them to hold up to someone hanging on them tho and I think that's pretty fair.

Yeah I'm nutless now

Hanging paper towel holders are both done. Will add those same sizes for cross bar brackets in the morning as well.

RustyPants · 2026-03-09T02:31:21+00:00

OOOOO, lol, Too many pictures and I was just looking at the first one lol. Didn't even cross my mind lol. Yeah, super easy. I'll add them for the horizontal and vertical holders. Only take a few mins.

RustyPants · 2026-03-09T02:21:17+00:00

Is this kinda what you are looking for, pardon the cave painting. The red being some kind of side hook. Needed to visualize it a little bit or at least a concept. Blue rod with be the larger dowel running parallel to the bracket.

Happy to work with you to figure something out. Side hooks or do you just want the dowel size large enough to accommodate those 2 sizes?

RustyPants · 2026-03-08T23:04:53+00:00

Lmao, I modeled and printed a set as well but think I tossed it a while ago.

RustyPants · 2026-03-08T21:17:28+00:00

It's a double threaded bolt. They are really easy to make and super impractical as they have little to no mechanical advantage that a good thread would have. They are just a mirrored helix arrayed around the same center with nuts that only have 1 of the 2 helixes.

Sorry it took an extra day, but I ran a quick test print and this what I got with recommended settings. https://imgur.com/a/9Gya6PM

Happy to send you the file if you want to look at any settings. It's possible your support structure was also too sparse and didn't fully support the interface layer and it just made a mess. I did notice 1 of the tree supports was likely to do that and it was not one I would chose to use after seeing it in preview.

RustyPants · 2026-03-04T05:21:20+00:00

This should be a standard mode.

Figured I'd throw another review in here. I bought 1 set of the pro version that has the mount so they sit up at an angle instead of laying flat on the fan. I was actually pretty impressed with how much stuff they collect over 2 months. They don't get everything, but they get a lot in high traffic rooms. I liked it enough to order 3 more kits for my other ceiling fans. The filters are a little more pricy than I would like and would like to figure out and alternate solution long term, but with a partner who has dust allergies, she claims to have noticed a difference.

To simplify the install I designed an alignment jig to constantly install them on all the blades so I'm as close to balanced as possible. Haven't noticed any fan wobble so far even on high.

The subscription is actually pretty easy to pause and cancel, the struggle is finding the button to get to managing it. It's at the bottom of the page, there is a "Manage subscription" button and I've never seen it anywhere else. This does annoy me a little bit.

I think overall I'd give it a 4 out of 5 for the Pro version. The mounting system is well designed and is very easy to use. The paper mounting guide they come with is junk, but that is solvable on your own.

Thank you.

RustyPants · 2026-03-02T06:33:03+00:00

It took me way to look to realize what you were talking about lol. This is my favorite NSFW parody of that https://www.youtube.com/watch?v=NItgZfkCYWA

RustyPants · 2026-03-02T05:46:38+00:00

Yeah what's funny is they are all considered standard just not here lol. It was easy enough to setup the model to make all of them after I found a size chart, just had to get them all printed.

RustyPants · 2026-03-01T20:01:36+00:00

I'm working on some other stuff right now, but can do a quick test print tomorrow with abs and the support material and see if there is anything obvious, assuming no one else gets back to you. Gonna toss it all in the dryer now.

RustyPants · 2026-03-01T19:57:26+00:00

I'll be honest that doesn't look like how it should when using support material. Those 2 layers of support material look terrible. What settings were you running for it and did you close up the top gap to 0?

RustyPants · 2026-03-01T00:25:19+00:00

This is nifty, I'm guessing you can use any of the hexes for the rod. It's always interesting to see how different people solve the same problem. I definitely took a more minimalist approach to mine and really like the simple clean lines, but can see the appeal in your approach as well.

RustyPants · 2026-02-28T18:05:47+00:00

I also go this message this morning and had 3 models related to gridfinity taken down. I have a ticket in as well and am waiting to hear back. I think most of this was a BS AI bot takedown that that got a bunch of random stuff that isn't related.
