Thrift Store CD Rack Turns Into Small Parts Storage Playground

March 17, 2024 by Dan Maloney 16 Comments

What in the world could an accessory for an obsolete audio medium possibly have to do with keeping all your unruly bits and pieces in order? First of all, we’re not sure the CD is quite dead yet; we’ve got about a thousand of them packed away somewhere, and we’re pretty sure they’ll be back in style again one of these days. Until then, though, the lowly CD rack might be just what you need to get your shop under control.

As [Chris Borge] relates the story, he stumbled over this CD rack at a thrift sale and quickly realized its potential. All it took was some quick design work and a bit of 3D printing. Okay, a lot of 3D printing, including some large, flat expanses for the drawer bottoms, which can be a problem to print reliably. His solution was simple but clever: pause the print and insert a piece of stiff card stock to act as the drawer bottom before continuing to print the sides. This worked well but presented an adhesion problem later when he tried to print some drawer dividers, so those were printed as a separate job and inserted later.

Sadly, [Chris] notes that the CD format is not quite Gridfinity compatible, but that’s not a deal breaker. He also doesn’t provide any build files, but none are really necessary. Once you’ve got the basic footprint, what you do with your drawers is largely dependent on what you’ve got to store. The video below has a lot of ideas for what’s possible, but honestly, we’re looking at all those little parts assortment kits from Bojack and Hilitchi piled up in a drawer and just dreaming about the possibilities here. Add a voice-activated, LED inventory locator, and you’d really have something. Off to the thrift store!

The Loveliest Electronics Desk You’ll See Today

September 21, 2023 by Kristina Panos 10 Comments

Does your electronics desk have a lap drawer? And is it filled with random, disorganized detritus? Well, [Handy Bear] is here to show you that you can put so much more in every drawer you’ve got if you do it right. And boy, it sure looks like [Handy Bear] did it right.

Hidden inside this beautiful antique desk is plastic storage compartment after plastic storage compartment, all situated inside custom dividers made painstakingly from 3mm MDF. The first iteration, a cubbyhole arrangement, was not modular and looked crappy by [Handy Bear]’s standards.

Back to the drawing board and the scroll saw. [Handy Bear] came up with a new scheme that mimics the dividers in the plastic storage boxes they’re using for components and more. In addition to the slotted parts are open-top boxes for things like the multimeter, helping hands, and the ever-important label maker.

[Handy Bear] used hot glue and simple joinery for everything, sealing all the seams with a mixture of glue and water to keep it from turning to dust. We especially like the caliper holder for the lap drawer. You’ll notice that not quite everything fits inside the desk, so [Handy Bear] put the bigger stuff on a couple of IKEA carts. Be sure to check out the short build video and take the desk tour after the break.

Don’t have room for a whole desk worth of stuff? Build an electronics lab in a box!

No Tool Left Behind With The Help Of Homemade Shadow Boards

June 21, 2022 by Dan Maloney 38 Comments

Shadowed tool storage — where a tool outline shows at a glance what’s missing from storage — is a really smart way to keep your shop neat. They’re also super important for cases where a tool left behind could be a tragedy. Think, where’s-that-10-mm-socket-while-working-on-a-jet-engine? important. (It’s always the 10-mm socket.)

But just because shadow boards are smart, doesn’t mean they’re easy to make. That’s why [Scott Prince] came up with this semi-automated method for making toolbox shadow boards. The job of tracing around each tool on some sort of suitable material and cutting out the shapes seems straightforward, but the trick comes in organizing the outlines given the space available and the particular collection of tools.

[Scott]’s method starts with capturing images of each individual tool. He used a PiCam and a lightbox housed, strangely enough, in a storage bench; we’d love to hear the full story behind that, but pretty much any digital camera would do for the job. After compensating for distortion with OpenCV, cropping the images, and turning the image into a vector outline of the tool, [Scott] was left with the task of putting the tools into logical groups and laying them out sensibly. After tweaking the tool outlines and adding finger cutouts for easy pickup, [Scott] put his CNC router to work. He chose to use a high-density polyethylene product made by his employer, which looks fantastic, but MDF would work fine too.

We have to admit to a fair degree of toolbox envy now that we’ve seen what shadow boards can do. We’re a bit torn, though — [Zach Friedman]’s Gridfinity storage system has a lot going for it, too.

Super Simple Scope Shambles Solution

April 29, 2022 by Jenny List 22 Comments

Sometimes the projects we write up for Hackaday require their creators to produce pages of technical explanation, while others need only rely on the elegance of the hack itself. The Scope Probe Caddy from [Tonyo] has probably one of the shortest write-ups we’ve linked to from a Hackaday piece, because its utility is self-evident just by looking at it.

Scope probe connector with 3d printed organiser attached. — The Hackaday Rigol gets the caddy treatment.

It’s likely that everyone who has owned an oscilloscope will have encountered this problem: that multiple ‘scope probes soon manifest themselves into a tangled mess, an unruly octopus which threatens to overwhelm your bench. The probe organizer is an extremely simple solution tot his problem, a 3D printed clip which fits over the probe connector and into which the probe itself can also slot.

The clip comes as an OpenSCAD file, which starts with a range of size definitions for different types of probe connector. The Rigol we have here isn’t among them, but a very quick measurement with the calipers allowed us to enter the size of a Rigol probe connector at 11.5 mm. It’s not often we make something we’re writing up as we’re writing it, but in this case a quick bit of 3D printing and we too have tidy probe storage. With the addition of a cable tie or a small nut and bolt it’s assembled, and now helps make a Hackaday bench a little clearer.

Once you’ve printed this organizer, you might want to turn your attention to the probe itself.

DIY Laptop Stand: Why Stop At One When You Can Slot Three?

April 24, 2022 by Donald Papp 15 Comments

We make the tools we need, and that’s definitely the case with [Marco Schulte]’s laptop stand. It slots not one, not two, but three laptops at once.

For all their portability, multiple laptops can be a bit clunky to manage on a desk, so [Marco]’s solution definitely saves space while keeping things accessible. The laptop in the front can be open for use and easy access, while the two in the back are held vertically and can be attached to external monitors or other peripherals.

Not only does it save space, but the stand provides ample spots to anchor cable ties for securing the inevitable mess of wires and cables that dealing with three laptops brings. It makes for a tidier desk, that’s for sure.

The stand was designed in Fusion 360 and was cut from plywood with a CNC router. Does this design give you any ideas, or would you like to make one for yourself? The design files are here.

No access to a CNC router? No problem if you have glue and some spare boxes laying around! You might be surprised at how sturdy a few layers of cardboard and glue can be.

A New Spin On Empty Filament Spools For Part Storage

July 5, 2021 by Donald Papp 26 Comments

Empty spools from 3D printer filament are the kind of thing that begs to be repurposed, and one option is [3d-printy]’s vertical filament spool parts drawer design. The way this solution works is by using the spool to hold twelve vaguely pie-shaped drawers that can be individually unlocked and removed entirely, which makes accessing their contents (or dumping them out) much easier. This method requires the spools to be oriented vertically, so it ends up handling a bit like a Rolodex.

One downside of the design is that it requires two inserts to be installed on the inside of the spool walls, which act as guide rails and lock points for the drawers. Another is that managing a vertical spool can be a bit awkward, given its lack of flat surfaces. Happily, there is an option for a matching stand that not only provides a flat base, but keeps any accidentally-unlocked drawers from falling out and spilling their contents.

The project files are OpenSCAD files, which allows easy customization for different spool manufacturers and dimensions, and [3d-printy] provides measurements for some common ones. Another nice element of this design is that no single part uses more than 30 grams of filament, which makes printing them an attractive way to use up the last bits of filament rolls.

We’ve seen drawer-style storage for filament spools before, but haven’t seen a design quite like this one before. Watch an overview of the drawer design as well as the spool holders in the videos, embedded below.

To Lovers Of Small Boxes: A 3D Printable Design Just For You

March 28, 2021 by Donald Papp 7 Comments

Print them at 50% scale for a far cuter (and much less useful) result.

[Jacob Stanton]’s design for 3D-printable, stacking and locking boxes is a great example of design for manufacturability (DFM). MicroStacks show how part of good DFM is taking the manufacturing method’s strengths and weaknesses into account. [Jacob]’s boxes are created specifically with 3D printing in mind, which is great design whether somebody is making one, or dozens.

The boxes have sturdy parts that all print without any need for supports, fasteners, or post-processing. In addition, since no two 3D printers are quite alike and some print better than others, the parts are also designed to be quite forgiving of loose tolerances. Even on a printer that is less well-tuned than it could be, the design should still work. The boxes also have a nice stacking feature: a sturdy dovetail combined with a sliding tab means that once boxes are stacked, they’re not coming apart by accident unless something breaks in the process.

The boxes as designed are about big enough to store AA cells. Not the right size for you? One nice thing about a 3D-printable design that doesn’t need supports is that it’s trivial to uniformly scale the size of the models up or down to match one’s needs without introducing any print complications in the process. You can watch [Jacob] assemble and demonstrate his design in the video, embedded below.
