Designed these spiders for halloween!

"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 😎

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
black windows in had

Your n migrated
- God, my autocorrect is so fucked. I can't type certain words without it "correcting" them. For example it almost always changes "ate" to "are". Drives me crazy.
  
  It also changes couldn't to could which has almost caused issues a few times

You nearly gave me a heart attack as i was scrolling. Safe to say, great job OP

I hope you've got good insurance, because someone is gonna burn down your house when they see these.

Fuck

You

TIHI!

Fuck you

Thanks, I hate it.

Wow well done! Freaks me out just looking at the pic.

This picture scared the fuck out of me.

Wow, these are great resolution!

These make me squirm. Good work.

Did you hear about the spiders in one of the ig Nobel prize winners?

Things getting creepy and crawly this year,

Mix a couple into the candy bowl!

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!

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.
What other creepy-crawlies are in your nightmares? just brain storming ideas 😈
- House centipedes.

Throw them at people like pocket sand

Was this in PLA?

Yup, printed in white then painted 👍

I just killed about that many real Black Widow's in my yard.

Well, that explains the fire...
Australia moment

Awesome, thx for sharing!

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.
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 👍
- Thank you so much for the awesome response! You were able to confirm a few of my guesses how done things were done and also given me a few new things I can read more about.

  After seeing the spiders and reading that mask thread, the print head retraction had me interested since I could apply some experience I did have, cake decorating, which thinking about it now, is fairly similar to 3D printing. You've got semi-solid but sticky ingredients, and the icing coming out doesn't just stop and cut off cleanly when you pull back from what you're working on. That's immediately what I thought of with your spider legs and how I thought you used it to your advantage.

  I find it so encouraging whenever I see this. It's always easy to see someone's end result and think that was just whipped out perfect on the first try. Most computer projects I do work this way, and I see lots of programming humor jokes that essentially say the same thing. "I'm not a good X, I'm a good Googler!"

  Hah, I'm glad you have that a look! The fingers were my favorite part due to the higher ratio of crispy bits!
  
  Thanks again for the great reply!

I know they're widows, but spiders are done to death. Do wasps instead.

I'll see what I can do!
