They are easy to print and can be shaped after for a realistic look. I used a .2 nozzle and dipped the legs in boiling water to bend them to shape.
"Aren't they awesome? Can you tell which one is the real one?"
"Haha yeah they're really wait what"
The black widows really get that screamish response that most bugs don't give me. There's something about that red on black that hits my primal buttons in a tizzy
The only other bugs that get me like that are the too many (more than eight legs) bugs. Milli/centipedes
Oh good their markings are working then
It's cool that you got into 3D printing, Satan
Nice. I hate it.
Omg those look so real. Ugh.... The legs are perfect. I hate it. Great job.
Redbacks? If you're deploying these in Australia then that is just evil.
As an Australian I had a heart attack before I read the title.
You don't just pick up a handful of redbacks, you fool! You kill them with fire and sleep with one eye open for the next month!
I had a teacher who like... owned or had something to do with running a store called Redback. Now that I think of it idk why he was a teacher with that kind of money. We found a redback in the classroom and he relocated it outside. Just in the yard. Where the children play.
Good times.
Don't worry, when I print them they will be left over white, left over Oreo, left over shiny blue, etc.
These guys are gonna look sick 😎
Nice! Hope you have insurance to pay for all those heart attacks you'll be causing
You nearly gave me a heart attack as i was scrolling. Safe to say, great job OP
Saw ~~brown recluses~~ black widows in had, didn't read title. You scared the everliving fuck out of me lol
Edit: wrong spider, duh lol
Black widows, not brown recluses
That's what I meant, oops lol
I hope you've got good insurance, because someone is gonna burn down your house when they see these.
TIHI!
Fuck
You
Thanks, I hate it.
Mix a couple into the candy bowl!
Wow well done! Freaks me out just looking at the pic.
Did you hear about the spiders in one of the ig Nobel prize winners?
Things getting creepy and crawly this year,
Wow, these are great resolution!
These make me squirm. Good work.
This picture scared the fuck out of me.
Fuck you
Am I the only one who has nightmares of someone else throwing a handful of spiders at them? It's not always spiders, but just for some reason, I've had recurring dreams of someone throwing creepy-crawlies at me. Just an irrational fear of mine, perhaps?
My recurring nightmare is my old school calling and telling me I only passed the final exams due to a grading mistake of theirs. Then they tell me, I have to take the final year again and I have to go back to school.
I graduated in 2007.
You get those too? I get a variant where I missed going to a class I forgot about and now I might not graduate unless I go back and finish.
I get that variant as well lol
It's always French class...
Life-like. Except for the dead one.
Which ironically makes them all look more life like
Unless it's playing dead, then it's not ironic because it looks very much like a living spider playing dead. Which also looks like a dead spider. Fancy that!
Throw them at people like pocket sand
Was this in PLA?
Yup, printed in white then painted 👍
Looks like resin printing
Awesome, thx for sharing!
I just killed about that many real Black Widow's in my yard.
Well, that explains the fire...
Australia moment
Haha, I love it!
I have zero experience with 3d printing, but I look at creative uses like this from time to time. After reading this mask printing post yesterday, are there any special considerations needed to be taken before printing tiny structures like those spider legs?
I see little spider "leg hairs" on some of them, and I think that really adds to realism of the spider, but would that be an issue in other prints?
If this is a really complicated answer, feel free to say so or if you can give me some technical terms for some of the potential issues, I have no problem googling them myself, I just wouldn't know where to start on my own.
Edit: If you are into harmlessly creeping people out at Halloween, you may have interest in my Meat Hand Meatloaf I posted the other day. It's a zombie hand meatloaf, which is great looking in a terrible way also, like the spiders!
Printing things is full of "special considerations". Those are not outliers.
Yeah, it still feels like a bit too much material science knowledge is required for your average person. That's what keeps me just watching you guys every time I get tempted to try it myself.
I do like learning about the different filaments and such though. I still find it very cool.
3d printing is all about balancing settings to maintain quality. Like layer adhesion vs quality/cosmetics.
You don’t have to get super technical if that’s not your thing, though some basics are very helpful- but you can learn that as you go.
If you have the time and the cash to get started… pick up decent printer and give it a go! If cash is a problem, many local libraries have printers you can use, or there’s hack spaces, etc.
Feel free to come here with questions. Everyone needs help at some point.
That's a great reminder to check again to see if there's a makerspace near me yet. It would be nice to get have other people with experience to learn from.
Thanks for being so welcoming!
It's really not. It seems daunting, but it's only as complicated as you decide to make it, really. I embrace the little hairs... or snip 'em off... or hair dryer them off... or zap 'em with a lighter. I could probably get technical as hell and set things up so there's no possible way it makes additional hairs or there's any tolerance for errors, but I'm not going to get that much into the minutiae. I print rings/jewelry, tchotchkies, structural stuff, gears for projects, etc.
You can get into the material science, but you don't have to.
There are a few considerations I do in the design phase to eliminate possible issues and clean up. Supports and rafts can effect surface finish unless you have nailed the settings, so I try to avoid this.
The legs are printed flat on the print bed, this gives strength to the legs and also helps with bed adhesion. Also helping with bed adhesion is the single outline of the spider, issues often occur during layer changes and so eliminating the amount of times the nozzle leaves the print the better.
The leg hairs are a result of the nozzle leaving the print to go somewhere else, leaving behind extra material that stretches thin as the print head moves away. There are settings to stop this from happening like print-head and material retractions, coasting distance settings and Z hopping.
Learning the material science can be done via a lot of trial and error ha, and google. With FDM printing, it's handy to know how thermoplastics work, but also knowing how your 3D printer works can result in more reliable prints.
There is always settings you will need to dial in, but I've found each individual print file can be tweaked to; make it print quicker, get better quality, make things stronger, give things more flex. SO MANY SETTINGS it can get a little overwhelming.
It usually goes, "google search 'why is x happening with my 3d prints'" "Answer: Adjust that setting you've been avoiding or didn't know about" or "you're printing too quickly" (slowing down prints solved most of my issues with quality, going against my need for speed)
Slicers (programs that you print from) usually give you a good description of what each setting does.
Meatloaf looked yum, wanted a finger 👍
