So my kids cut the legs off one of my articulated bugs (https://www.thingiverse.com/thing:2817607) and it actually looked pretty cool. So I modded the bug... into a slug :D

Prints fine hollow, but 100% infill gives it a realistic weight.

Tip for removing from your printer: Stick a putty knife between two body segments and twist it. This should be enough to pop them loose.

UPDATE #1: There is now a file with a slightly rounded tail - safer for youger kids ;)

UPDATE #2: WuffyUnikitty designed a clip-on snail shell for these little guys. Check it out! https://www.thingiverse.com/thing:2899318

there is no problem very good :D

Hey, I'm a primary school teacher and want to use these with the really young kids and their counting. Am ok to separate the slug, and then add/ remove some of the centre links to make them longer/shorter?
Hoping to put them up on here if that's ok, to share as a teacher resource. Obviously I'll link back to your page, just thought I'd run it by you first!

Absolutely! Go for it :D

I chose your slug as my very first 3D print, and I love it! We have a group of 150 elementary school kids coming through tomorrow morning, so I want to print more to give them something cool to handle. Thanks so much for this!

Not only did the slugs survive the demo, they were so interesting that it kept them from touching the STEM class guitars on the table. I told them about Thingiverse so some may look you up.

Great! Dual-purpose slugs! Looks like you had quite an interesting session with them. Great looking work space you all have there :)

Awesome! 150 kids will be a true stress test for the articulations ;) I hope it goes well and you see that look of wonder in their eyes!

Awesome! Made a gang of them, they're cute as a button! I'll hope soon they'll be united for a family picture.

For sure! I'd love to see them :D

You have infected me with The Bug ;)
Here is my latest mod.
My wife thought it needed legs!


A great little critter :)
I've added a magnet so he can hang on the fridge (along with all the geckos I've made) :)

Magnetic Slug

Brilliant! Here I go on a shopping spree for magnets :D

I am about to make this! I think students will love it as a fidget tool... I saw that you printed it using a Qidi printer, I am just curious if you use their software for slicing, or something else? I just got my printer setup and I find the slicer quite clanky... I also have not been able to figure out how to set which extruder I want to use, as I have a dual extruder... I would appreciate any tips

Oh boy, yeah - I took one look at the slicer they provided and immediately bought Simplify3D. I didn't know the first thing about slicers and settings, and S3D got me up and running pretty quick. It's not cheap, but it was worth it to me to simplify my learning curve and give me lots of options/control now that I know what I'm doing. If you end up buying it, open up the Factory file below (that's what they call their project files) and take a look through the settings. They're what I typically use for a model like this. It's set to print a single skirt outline to make sure the filament is flowing nicely, then two perimeters with 15% infill. The first layer prints nice and hot at 215 degrees (60 degree bed temp) to get good adhesion to the bed, then the rest of the layers print at 205/40 degrees. Also, the first layer prints taller and slower (again, for good adhesion). Probably overkill for a simple model like this, but they're kind of my default settings nowadays.

If you don't end up getting S3D, load the gcode file below into your Qidi Tech I and it should print nicely!

Unfortunately, I've never used a dual extruder machine so I can't be of much help there.

Thank you for the recommendation! My 3D printer was funded from Donorschoose.org, so I am about to put a project for the software next... The Qidi software is just horrible... I will however print the slug before I get the new software, because it is just too nice to wait! Thanks again!

Oh wow, that's really awesome! What a cool organization! Good luck with the print - I hope it turns out great :D

This is my favorite fidget toy. I seriously can’t put it down. Thank you!!

You're welcome! I'm the same way with it - I keep one at my desk and fidget with it constantly when I'm on the phone ;)

+100500 for the best fidget so far.
Really amazing work, thanks a lot!
BTW, Have you considered making a caterpillar?

My printer crapped out just before finished this print, but it at least finished all the hinges and it still works quite well. Soon as I fix my printer I might print another one. Thanks for sharing this!

Bummer! I hope you get it going again soon. I've only had two major crapouts in my 3D printing life, and they were both very sad times ;)

Hey ist it possible to get a file with 10 or 12 sections? Printed one in 50 and one in 200%. But a longer one would be really cool

Such a nice design, my kids love it.
I like to heat the feelers with a hair dryer and bend them upwards

Great idea!
While we're on the subject of making it less "flat": is there a design that is more rounded so there aren't sharp edges?
Maybe print two of them and glue them together?

Unfortunately, I can only get this to bend the opposite direction than the picture, and one of the pieces broke when I tried to bend it the way you show there

Nice design.. Any chance you could make longer versions?

Is it made in one piece or more than one?

It prints all at once and the pieces interlock as it builds. So they're six distinct sections, but they'll all be connected by a pin that goes through a hole. Just pry it up and it articulates :D

Thanks AnaErwin! It's been so fun sharing on this site and seeing all the "makes"! :D

You should try and make it so that it can move in all directions more
