We’ve covered a number of projects that assist makers who need to fill orders for their small businesses, or kitting. [Helmke] has sorted thousands of pieces of hardware that they include with 3D printed parts sold online. They have been developing an alternative, a modular system for sorting and packaging specific quantities of parts.
After the break, check out the latest video from their small but growing channel for a very clear walk-through of the counting system they’ve been iterating on. The 2nd video in the series explores solenoids, Geneva drives, and ultimately a sprocket to dispense a variable number of bolts from the sorting machine. The approach gives consistent results, easily to vary quantities, and is fast! These videos are also rich with lots of small details you might want to explore on your own like magnetic part feeding, discussions of different sensors for detecting and counting parts, 3D printed gear box designs, and we love the use of stackable crates for project enclosures.
We hope to see more videos from [Helmke] in the series as the project matures for deeper dives into the existing mechanisms and new features they develop next. Hungry for more? We’ve brought you everything from cutting and stripping wire, to SMD tape, to resistors, to laser-cut parts. Continue reading “Dispense 60 Bolts In 2.3 Seconds” →
3D printers have come a long way from cranking out things like bottle openers and coat pegs, and [E. Soderberg]’s Print in Place Geared Hinge is a pretty nifty demonstration of that. This hinge is designed as a print-in-place part, meaning it is 3D printed as a single piece, requiring no assembly. Not only that, but the herringbone gears constrain the sturdy device in a way that helps it support heavy loads.
Of course, hinges — even strong ones — are not particularly hard to find items. They’re available in a mind-boggling array of shapes and sizes. But what’s interesting about this design is that it shows what’s easily within the reach of just about any hobbyist nowadays. Not that long ago, designing and creating an object like this would not have been accessible to most home enthusiasts. Making it without a modern 3D printer would certainly have been a challenge in its own right.
It doesn’t always matter that a comparable (or superior) off-the-shelf part is available; an adequate part that can be created in one’s own workshop has a value all its own. Plus, it’s fun to design and make things, sometimes for their own sake. After all, things like 3D-printed custom switch assemblies would not exist if everyone were satisfied with the ability to just order some Cherry MX switches and call it a day.
Why buy a bed when you can make an even fancier one — with a hidden compartment!? After [Vitiello] couldn’t quite find a bed frame he liked, he decided to make his own, using a herringbone pattern for the woodwork.
We’ve shared quite a few awesome home-made kid’s beds lately, like this beautifully hacked IKEA bed (complete with a hidden room!) and this Avenger’s themed Helicarrier bed, featuring a remote control dart turret. So after we got over feeling jealous that we weren’t three feet tall and able to have a bed as awesome as those, we saw this herringbone bed. And while it doesn’t have a hidden room, it does have a pretty awesome secret compartment which helps ease the pain.
Built out of about $250 worth of cedar planks, [Vitiello] did a great job with both the design and build. He purposefully made the headboard rather thick to accommodate an LED lit shelf, and of course, the hidden compartment accessible from the side. And since he could, the LEDs are remote controlled — and of course color changing.
