Student 3D Prints Eyes

[Ondřej Vocílka] is a student at the Brno University of Technology in the Czech Republic.  In addition, the 23-year-old lost his vision in his left eye. While attending a lecture on 3D printing, he wondered if he could 3D print an ophthalmic prosthesis — an artificial eye. Turns out, he could. If you don’t speak Czech, you’ll need to call on a translation service like we did.

Unlike conventional glass or plastic eyes, it is trivial to change parameters like color when 3D printing the prosthetic. This is especially important with the iris and the finished product takes about 90 …read more

Arduino Keyboard is Gorgeous Inside and Out

While the vast majority of us are content to plod along with the squishy chiclet keyboards on our laptops, or the cheapest USB membrane keyboard we could find on Amazon, there’s a special breed out there who demand something more. To them, nothing beats a good old-fashioned mechanical keyboard, where each key-press sounds like a footfall of Zeus himself. They are truly the “Chad” of the input device world.

But what if even the most high end of mechanical keyboards doesn’t quench your thirst for spring-loaded perfection? In that case, the only thing left to do is design and build …read more

Repairs You Can Print: Floor Lamp is Now Several Shades Better

We all have that one possession—maybe more than one—that we’ve had forever and refuse to let go of, even though it has seen better days. When that something is a useful appliance, it can be heartbreaking to watch it deteriorate. For [Elmojo], that thing is a 10+ year old Medusa-style floor lamp. It still looks and works great, but the plastic shades are crumbling. The good news: [Elmojo] has a 3D printer.

Here’s where things get exciting. Not only did [Elmojo] have a pretty good chance of making new shades that would work, he had a chance to change the …read more

The Latest 3D Printed Fad: Flexible Armor And Pangolin Cosplay

Last week, [David Shorey] came along to the monthly Hackaday meetup in Pasadena. These meetups feature speakers and drinks, projects and chit-chat, and sometimes a few demos of what the local Hackaday community has been working on. [David]’s impromptu demo was something no one had ever seen before. It’s 3D printed tiles embedded in fabric. This is the beginning of 3D printed flexible armor, a great method for cosplay builds, and a really cool way to add another trick to your 3D printing toolkit.

The steps to reproduce this project are actually very easy. The most important bit is the …read more

Printed Adapter Teaches an Old Ninja New Tricks

Do you like change for the sake of change? Are you incapable of leaving something in a known and working state, and would rather fiddle endlessly with it? Are you unconcerned about introducing arbitrary compatibility issues into your seemingly straight-forward product line? If you answered “Yes” to any of those questions, have we got the job for you! You can become a product engineer, and spend your days confounding customers who labor under the unrealistic expectation that a product they purchased in the past would still work with seemingly identical accessories offered by the same company a few years down …read more

Repairs You Can Print: Fixing a Rat-Attacked Mic Cord

We’ve all been there — a steamy night in the rainforest of Papua New Guinea, sweaty slumber disturbed by the unmistakable sounds of gnawing. In the morning we discover that a rodent of unusual tastes has chewed the microphone cable of our transceiver right half in two, leaving us out of touch with base camp. If we had a nickel for every time that’s happened.

It may sound improbable, but that’s the backstory behind [Marius Taciuc]’s 3D-printed mic cord repair. Even with more mundane failure modes, the retractile cords on microphones are notoriously difficult to fix. Pretty much any of …read more

Repairs You Can Print: Model Coal Car Fix

Model railways are a deep and rewarding hobby, and the mechanisms involved can be both surprisingly intricate and delightful. A great example that may surprise the unfamiliar is that of model train carriages, such as coal cars, that are capable of both receiving and dumping a load at various points on a model layout. This adds realism and, if we’re honest, just plain old fun.

When [Phil]’s father received his Lincoln coal car from eBay, it was unfortunately damaged, and incapable of dumping properly. Instead of throwing it away, a replacement part was developed and 3D printed. The part was …read more

Repairs You Can Print: A Little Love for the Glove Box

A few years ago, [Brieuc]’s car blew a fuse. He went to replace it, which unfortunately means removing the entire glove box. In his haste to get his baby back on the road, he accidentally broke one of the clips that holds the glove box on the dashboard.

[Brieuc] tried to just glue the thing back together, but it didn’t hold because the part has to flex a little bit for people who need to get into the fuse box. No one seems to offer a replacement for this small but vital hunk of plastic, though he did find someone …read more

Repairing a Wounded Mantis

While it’s true that we didn’t specifically say making Hackaday staff exceedingly jealous of your good fortune would deduct points from your entry into our ongoing “Repairs You Can Print Contest”, we feel like [Sam Perry] really should have known better. During a recent dumpster dive he found an older, slightly damaged, but still ridiculously awesome Mantis stereo inspection microscope. Seriously, who’s throwing stuff like this away?

Apparently, the microscope itself worked fine, and beyond some scratches and dings that accumulated over the years, the only serious issue was a completely shattered mount. Luckily he still had the pieces and …read more

A 3D Printable Raman Probe

Scientific instruments are expensive. In a lot of cases, really expensive, so if you have spent any time in a well-equipped lab, the chances are that it would have been one backed up by the resources of a university, or a large company. Those experimenters who wish to pursue such matters outside those environments have traditionally had to rely on obsolete instruments from the surplus market. A fascinating endeavor in itself, but one that can sometimes limit the opportunity to pursue science.

It has been interesting then to see the impact of the arrival of affordable 3D printing on …read more
