Are you bored of 3D printing life hacks, Gridfinity bins, and other useful objects? Let your inner fool flourish with some of the most annoying 3D prints you can make, from loud and obnoxious to obtuse and irritating.Aztec death whistle A model so bad I printed two of them The Aztec death whistle, also known as the ehecachichtli, is a whistle that was discovered in the 1990s at an Aztec dig site in Mexico City.The original is thought to make a sound akin to the wind, but thanks to an inventive naming convention, has taken on something of a life of its own as a shrill, high-pitched scream.
As a result, the whistle has become a pop culture reference in movies like (2021) and (2025).Printing your own death whistle is absolutely worth it if you want a way to make a truly horrible noise.I printed an Aztec death whistle for my partner who loves horror films and spooky things; it’s been a hit.
Curious to see how other models sounded, I then printed a second which doesn’t look anywhere near as impressive but sounds even worse.Print and hand them out on Halloween if you dare.Hand-cranked air raid siren Your neighbors will hate you There’s something truly eerie about the sound of an air raid siren, more broadly known as a civil defense siren.
Originally designed to warn of bombing raids during the Second World War, similar devices are still in use today and used to warn of dam failures, tsunamis, avalanches, and (probably) apocalyptic zombie outbreaks.You too can make your own loud and annoying hand-cranked air raid siren with just shy of 600g of filament, five metal bearings, and 11 M2.5x6 countersunk screws.This particular version is a remix of the original with a higher quality print profile, different infill pattern, and an optional improved hand crank The reason I’ve led with this remix is due to the video that one user provided showing the air raid siren in action.
There’s also a baby air raid siren remix for smaller hands, so that young children can be annoying too.Puzzle gift boxes Some people will love the challenge The trend of very annoying puzzle gift boxes is very much alive on model repositories like MakerWorld and Printables.These typically involve placing a relatively small gift (like a gift card) inside the box, and then gifting it to someone who then has to figure out how to get inside.
While they could just smash your PLA monstrosity to bits, the real fun comes from watching them run into constant roadblocks.Though rewarding puzzle boxes exist, these are far more frustrating—often relying on hundreds of screws and countless layers to keep the recipient busy.There are tons of these available to download and print, many of them requiring quite a bit of filament (and thus a real commitment to the bit).
This 120 screw gift box is a 1.5KG print, though there are others that clock in at around half of that or less.There are also much smaller annoying gift tubes and boxes designed specifically for gift cards.The worst Benchy When Benchy isn’t bad enough Benchy is a pretty annoying print in that most people make way too many of them.
Though it’s a fun first print that feels like a rite of passage, modern 3D printers have moved past Benchy and no longer need their abilities measured by how well they can replicate a toy boat.Regardless, bad Benchy models are even worse by design.Not only are you producing a benchmark print that’s designed to look bad, but you have the potential to annoy other people with it.
Try leaving one of these on a friend’s print bed when you next visit their house and see what happens.I found two great (terrible) bad Benchy models.The first includes a checklist of things you absolutely do not want to see on a Benchy: layer shifting, elephant’s foot, stringing, uneven surface blobs, artifacts, and overlapping layers.
The second looks like a Benchy that has been in a house fire.Both are perfect bad luck omens.Articulated dragons This is my list, not yours Maybe you love articulated dragons and other 3D printed slop.
Personally, I can’t stand it.I’m not going to judge you for making a few dust collectors to put on your shelf, but my blood pressure rises a little bit whenever I walk around a market and see an Ender V3 printing another freebooted MakerWorld dragon.Not only have I seen these in K-Mart (we still have K-Mart here in Australia), but also at my local Post Office.
They’re very often low-quality prints made with the cheapest filament that breaks the second it hits the floor from waist-height.They’re landfill waiting to happen, and isn’t that the most annoying thing of all? Kids seem to love them, but surely they’d be much happier with an Aztec death whistle or air raid siren instead.Noisy fidget toys Great for you, terrible for me I’ve resisted the urge to 3D print too many fidget toys, though I do love my infinity cube.
I also made a spinning top that spins for minutes if you put enough force into it, and my cats absolutely love it.One thing I see posted a lot on MakerWorld are clicky fidget toys, and I totally get it.Clicky things are satisfying.
I’m always playing with an AirPods Pro case or car keys in my pocket.I’m probably the perfect candidate for a clicky button or fidget blowback gun.But I know that if there was someone else in the room playing with these things while I was trying to concentrate, I’d probably say something I later regret.
Then again, the fidget blowback gun does look pretty satisfying… Bambu Lab PLA Basic Filament Bambu Lab's PLA Basic filament comes in a wide range of colors and ships on a reusable plastic spool.With embedded RFID chips in each spool, you simply place the filament in the AMS and your 3D printer knows exactly what it's working with—down to the color.$23 at Bambu Lab $23 at Best Buy Expand Collapse Bambu Lab AMS 2 Pro A multi-material system for Bambu Lab printers with active air vent 65°C filament drying, air-tight filament storage, a brushless servo feeding motor, Bambu's signature RFID filament sync, and compatibility with up to up 24-color/material printing by connecting more AMS 2 Pro units.
