sticky situation

Walls are too thin for a bottle and with the cut for r&i I would expect it to have issues at the seam. Even with this, the seam requires holding until it starts to get touching contact. Maybe if the bottle is extended past the 45°-50° tangent it would do a little better but then it has drop potential, especially with this PC/ABS blend and no part fan in an enclosure.

Thanks so much. I did not know the original purpose of the profile. In my experience with 3d printing, the buttress profile strength is in the opposite orientation when printed vertically. The additional length of the tapered profile creates a better distributed load across more layers of the stretching member/fastener. Still, I will prioritize overall printability without supports over thread directional orientation in most cases. I’m usually using a very large custom sized thread where the thread strength is irrelevant.

Like here in my laptop GPU water cooler project, I am using a buttress thread and spline to retain the cooling block and pump.

Printing like this is a fun start on the path of thinking about what is possible.

In FreeCAD, there is Mark’s Thread Design workbench. That includes a thread profile called the buttressed thread. The profile has a print orientation where, if you print it vertical, the thread will not produce any overhangs, like if a normal thread profile is > a buttress thread is 7. Mark has a YT upload on how to use his workbench. It is pretty easy to follow and a simple one to use.

At the stage I’m at in design, built in clips can replace most hardware. If I’m using printed threads it is usually a very large thread with some thin sleeve like clearance. I like to build splines into my threads to also create locking elements in the same space.

Yeah, I’m kinda volunteering for the mod part. In truth I think it would take the respective instance admin setting up such a thing specifically. Like create a throwaway or something so that the actual user is not propagated to other admin or the full activity pub feed being transported. The one instance admin would know and have the ability to filter or block, but that information would never escape the one server. As a mod I would be blind to actual potential bad actors and only filter at the liberal community and comments level. So basically a normal community that replaces the OP name with Anon, and never shares the real ID with anyone.

I keep seeing people go to the effort of creating a throwaway account to say or post stuff they want or need to externalize on the threadiverse. I’m willing to bet that for every person that goes to that much effort, there are likely somewhere between 10-100 people that lack an outlet and motivation to do the same. Greentext is just a mutual pretext on my part for genuinely caring about people under pressure right now and in need of an outlet in a way that is not really well supported by the fediverse or activity pub.

We are small enough here that regular names and people can hold meaning in familiarity and memorable history. Kind words and social interaction anonymously from these may hold considerably more value and meaning within this social dynamic that is not afforded elsewhere.

Think it has a hole, a shithole, in need of a shitpost. Fucking worthless gas chamber shit is a resignation of all life rights

Close the fediverse, we already had a solution

Nice eye, expression, and the subtle details that support that direction of gaze

I have no skin in this, but VC is involved with Bambu, as I understand things. That never goes well for consumers. They backpedaled to slow down the path to closed garden exploitation, but took no steps to open source or sell a legitimate product that can be owned. The solution is unplug it from the internet cause we gonna do what we gonna do ^{(fu fu)}

Build a Voron and own it for life. I know the excuses, but burning ownership-money, only to rent what someone else controls is mental. In the big picture, that is willingly selling your right to citizenship for neo feudalism as a slave to an overlord. It really is that simple. Normalizing that dystopia hurts everyone else too. But hey you do you. I’m happy for ya if that is your cup of tea.

dichotomous thinking is the pretentiously fun term

That is the kind of example that should be in the manpage. Thanks

Smooth prusa powder coated works great.

Drying makes a gigantic difference. It only takes around an hour in the open before TPU changes significantly from any ambient moisture and become visible in the print.

If you can control the moisture to a minor degree, you can alter the mechanical properties significantly. Once you hear popping, you’ll likely start blowing holes in prints, but there is a stage before this where the bubbles of gases are present but are not coalescing into the larger audible voids of escaping steam. You will see this on long prints using dried TPU filament left out in the open. There will be a much tougher start to the print that gradually degrades into a slightly softer and more flexible texture. It will likely turn slightly foam-like spongy rubbery soft for a section and then it will start popping and dropping walls with holes in the structure.

If you write down the room temperature and humidity and note the time it takes to get to this moisture property, it becomes possible to alter the flexible properties or empirical hardness of a TPU to make it behave in off label ways. This is essentially creating your own rudimentary foaming or light weight filament. It works best for vase mode or other small single wall structures. I have used this based on intuition alone. I imagine with a bit of record keeping one could control the humidity of a box to do longer prints within this state of foaming softness. I don’t know of anyone using a humidifier like the ones for acoustic guitar cases or cigars in a filament box, but that would be an interesting thing to play with too.

Leaves echo chamber ahhh WTF!

I post hobby stuff I’m working on. Everybody seems to care very little. I try to say stop being assholes and people hate for it.

Bias here seems typical for tech geekigarchy. After 2 years on Lemmy – echo chambers are also self selecting and self filtering.

“Randomize seams” uhh no, design parts with seams in mind if they are critical. I often add a small 0.3mm double chamfer “zipper” on a surface because it will accommodate the inconsistency and reduce it by forcing the root inside the body. I’ve made my own infill structures and patterns lately too.
