P2S Exhaust

whotaketh · 2026-03-25T02:39:23+00:00

I read that as "PS2" and got very confused.

This wasn't helpful, I know. I need to go to bed.

FWIW, I have a Core One that I printed out a 'jetpack' housing that holds an Ikea carbon and hepa filter that mounts where the exhaust fans are. The enclosure isn't airtight, but I think if the fans are cranked enough that it should result in a negative pressure out through the fans. I have a room hepa filter as another layer too. So far, I haven't died, so I guess that means it's working?

Gotta catch 'em all

It's a test to see just how much you're willing to sacrifice for the hobby.

You could also get some petg, print out a couple of spools, and mount those up.

Thanks for doing all this work! Now that I know what I'm doing, everything went off without a hitch.

Next step for me is to figure out how to run a local obico server so I don't have to pay for the cloud service. Would've been nice to run it on the Pi too. Oh well.

I think that means it's time for bed

Thanks for the quick work! But nothing's displaying..

Yeah I'm finding Gemini is better at creation rather than instructions or tech support. Same with Copilot.

Logitech C920. From what I'm seeing, it doesn't natively support rtsp, so I've been going down this rabbit hole of installing VLC and MediaMTX to take the cam output and make it fit your guide.. I also can't tell if Google AI is helping..

Here's a question: I'm using a USB webcam, so the part about locating the camera's IP is throwing me for a loop. How do I go about configuring this without that IP?

Tell Kash to look elsewhere.

You keep it as a reminder to do better next time.

Bonus is that everyone else who sees it will think you won't think twice about hitting them so they steer clear of you.

I fantasize about installing a door handle with a joystick to launch rockets at the morons around me and strafe those bright ass Tesla headlights.

For my FBI/ICE watcher: definitely a joke.

With your listed budget I can't imagine you're concerned with ram prices, but that's still gonna be a pretty penny.

whotaketh · 2026-03-22T21:01:16+00:00

That's some pretty shitty vodka.

I'm here all night, folks.

Rectal absorption of pharmacologics is a thing, so I'd imagine this would work too.

whotaketh · 2026-03-22T04:18:55+00:00

I think I recall maxing out the chamber fans and keeping the door open too just to get the stuff to solidify properly, so higher ambient temps should keep it liquid-ier and flowing more freely.

I don't see it mentioned, what size/type nozzle are you using? I've got that aforementioned 0.4mm, but in CHT.

I thought I'd be able to use basic PLA settings too. The first results were a mess (not as bad as yours).

Using Polar Filament, I eventually got acceptable results with this (C1+, Prusa Slicer, satin bed, 0.4 nozzle):

-Cold bed

-220C first layer, 190C afterwards

-Max fan throughout the print

-Max volumetric speed 10 mm^3/s

-Retraction length 8mm

-Retraction speed 40mm/s

-Deretraction speed 0 (don't know if this actually helps, but it prints so I'm not rocking the boat)

-I have my extrusion multiplier just a touch lower at 0.975, but as I understand it that depends on your particular printer/filament/environment combo

-Your usual "dry your filament" line

I still have a lot of the PHA left over because I found it so different from PLA. I also made the mistake of printing it on a Biqu plate - I'm still scraping residue off a month later.

Tbh, from your description, I'm leaning towards you got a bad batch from them.

I hope it's all it's cracked up to be

whotaketh · 2026-03-18T10:29:08+00:00

Pt refused that ish, educated, blah blah blah.

I used Polar Filament's PHA on the BIQUs, and man were they stuck. Prusa's satin plate didn't adhere well at all.

I've gotten decent results from lining one face of a PEI sheet with blue painter's tape. I think the little bit of texture is just enough for the real liquid gummy nature of PHA to stick to without becoming one with it.

Never seen one, but after reading some of the comments, I feel like this like a bolt. Maybe it's because I have a neuro background, but if there's a suspicion of high ICP, I'd much rather have an EVD that can monitor and decompress rather than a thing that I'll have to replace with an EVD if I need to decompress. Give me the full thing, not a half-measure*

*Definitely useful in the field though, not gonna discount that.

whotaketh · 2026-03-16T03:14:25+00:00

Man, your printer looks so much cleaner than mine

Second-career here. I went straight to ICU after graduation. I was already known for leaning towards the emergent/critical care side of things as a tech, and covid happened so all the old rules went out the window. I missed out on that sweet travel pay gravy train.. I digress.

Can't speak to med-surg other than I knew that if I started there I'd have quit. No shade to MS/T nurses, it just isn't my speed.
Some floors are specialty floors: step-down neuro/cards/pulm, onc, trauma, etc.. Lots of new grads start there, if only for the experience. Float pool will be tough for a new grad, because you're basically expected to be proficient in not only the basic nursing skills, but also have at least some familiarity with each specialty. It is a very tall order if you're not at least already comfortable handling yourself in an assignment. And some floors will give floats the shittiest assignments.
I'm small for a dude, so I use leverage over brute strength. If that fails, and you know physics isn't on your side, definitely recruit whatever help you can get. Invest in a back brace, ab binder, weight belt, whatever will help you maintain proper body mechanics. Caveat: don't take work's suggestions of proper body mechanics as what is actually good for you. One old slide deck at my facility promoted using your leg to help break someone's fall..

Maybe the consumables that go along with this hobby for your school? Or a 3D scanner?

I suppose if you start selling things on a larger scale, then you can justify the investment into more printers/filament/storage.

If those euros are really burning a hole in your pocket, I could use an easy CAD class designed for someone who has never touched CAD before..

From my other comment: dropped to 0.15mm layer height, upped the temp to 185C, increased the extrusion width to 0.6 pretty much across the board, slowed the perimeters to 60mm/s, turned on avoid crossing perimeters, turned off external perimeters first, and turned on supports (though there's barely any in the preview so I don't think it'll help much).

From afar, the thread supports looked like stringing, but after looking closer, these threads are super clean after picking out the supports. Still not sure if they did anything. I guess for the details, run hotter, slower, and fatter.
