Customize All the Fan Covers You Never Knew You Needed

Posted on by

Do you need a fancy fan cover with precisely specified attributes, but have no desire to design one from scratch? If you answered yes (or no) then [mightynozzle] has the answer. The Customizable Fan Grill Cover is a parametric design in OpenSCAD that allows adjusting the frame style, size, and grill pattern for any fan cover one may possibly need. [mightynozzle] also went the extra mile to provide a large number of pre-made STL files for a variety of designs in a wide range of sizes, so those who don’t want to fuss with customizing can simply download and print. …read more

A True 3D Printed Weather Station

Posted on by

If the term “3D printed weather station” makes you think of a printed enclosure for off-the-shelf sensors, don’t feel bad. We thought the same thing when we first read the message [Rob Ward] sent in about his latest project. Surely he couldn’t mean that he actually printed all the principal parts of a serious weather station setup, such as the wind vane, anemometer, or rain gauge?

Except, on closer inspection, that’s exactly what he did. Every part of the weather station is designed in OpenSCAD, printed out, and infused with various vitamins to turn them into functional pieces of hardware. …read more

Look Upon Eyepot, And Weep For Mercy

Posted on by

Hope you weren’t looking forward to a night of sleep untroubled by nightmares. Doing his part to make sure  Lovecraftian mechanized horrors have lease in your subconscious, [Paul-Louis Ageneau] has recently unleashed the horror that is Eyepot upon an unsuspecting world. This Cycloptic four legged robotic teapot takes inspiration from an enemy in the game Alice: Madness Returns, and seems to exist for no reason other than to creep people out.

Even if you aren’t physically manifesting nightmares, there’s plenty to learn from this project. [Paul-Louis Ageneau] has done a fantastic job of documenting the build, from the OpenSCAD-designed …read more

3D Printed Stethoscope Makes the Grade

Posted on by

On the off chance that initiatives like the Hackaday Prize didn’t make it abundantly clear, we believe strongly that open designs can change the world. Putting technology into the hands of the people is a very powerful thing, and depending on where you are or your station in life, can quite literally mean the difference between life and death. So when we saw that not only had a team of researchers developed a 3D printable stethoscope, but released everything as open source on GitHub, it’s fair to say we were pretty interested.

The stethoscope has been in development for several …read more

Printed It: Custom Enclosure Generator

Posted on by

You’ve written your firmware code, etched your own PCB, and now it’s time to put that awesome new project of yours into an enclosure. Unfortunately, all you have is a generic Radio Shack project box that you picked up when they were clearing out their inventory. If you put your project in that, it’ll have all the style and grace of a kid wearing hand-me-down clothes. Your project deserves a tailor-made enclosure, but the prices and lead time on custom plastic enclosures are prohibitive for one-off projects.

In Ye Olde Olden Days, the next step might have been to start …read more

OpenSCAD: Tieing It Together With Hull()

Posted on by

What’s your favorite OpenSCAD command? Perhaps it’s intersection() or difference()? Or are you a polygon() and extrude() modeler? For me, the most useful, and maybe most often overlooked, function is hull(). Hull() does just what it says on the can — creates a convex hull around the objects that are passed to it as children — but that turns out to be invaluable.

Hull() solves a number of newbie problems: making things round and connecting things together. And with a little ingenuity, hull() can provide a nearly complete modelling strategy all on its own. If you use OpenSCAD …read more

Repairs You Can Print: Broken Glue Gun Triggers Replacement

Posted on by

Picture this: you need to buy a simple tool like a glue gun. There’s usually not a whole lot going on in that particular piece of technology, so you base your decision on the power rating and whether it looks like it will last. And it does last, at least for a few years—just long enough to grow attached to it and get upset when it breaks. Sound familiar?

[pixelk] bought a glue gun a few years ago for its power rating and its claims of strength. Lo and behold, the trigger mechanism has proven to be weak around the …read more

When a Skimmer Isn’t a Skimmer

Posted on by

I have a confession to make: ever since the first time I read about them online, I’ve been desperate to find an ATM skimmer in the wild. It’s the same kind of morbid curiosity that keeps us from turning away from a car accident, you don’t want to be witness to anyone getting hurt, but there’s still that desire to see the potential for danger up close. While admittedly my interest is largely selfish (I already know on which shelf I would display it), there would still be tangible benefits to the community should an ATM skimmer cross my path. …read more

Try This for 3D Printing Without Support

Posted on by

Have a look at the object to the right. Using a conventional fused deposition printer, how would you print the object? There’s no flat surface to lay on the bed without generating a lot of overhangs. That usually requires support.

In theory, you might be able to print the bottom of the sphere down, but it is difficult to get that little spot to adhere to the bed. If you have at least two extruders and you are set up to print support material, that might even be the best option. However, printing support out of the same material you …read more

If 3D Printer, Then Custom Aluminum Extrusion Brackets

Posted on by

Aluminum extrusions are a boon for mechanical assemblies, but they require a stock of brackets and other hardware to be kept on hand. [mightynozzle] has decided to make things a little easier for prototyping and low-stress assemblies by creating a collection of 3D printable brackets for aluminum extrusions. 3D printing your own bracket hardware means faster prototyping, and if the assemblies don’t need the extra strength and rigidity of metal brackets you can just stick with the 3D printed versions.

The files are on Thingiverse, and include STL files of common brackets as well as an OpenSCAD script for customizing. …read more
