Repairs You Can Print: Nintendo DS Lite With New Battery And Case

The problem with hanging on to old consumer products is that the original batteries no longer hold a charge. To make matters worse, replacement batteries ordered online have likely been sitting on a warehouse shelf for years and are no better. [Larry G] faced this issue with his old Nintendo DS Lite. Luckily he remembered a hack from his youth where a friend’s Dad had duct-taped a massive alkaline D-cell battery pack to the back of a Gameboy to give it a longer life. And so [Larry] gave new life to his Nintendo DS Lite by designing and 3D printing …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

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: Fixing a Chewed Up Remote

What is it about remote controls? They’re like some vortex of household chaos, burrowing into couch cushions while accusations fly about who used it last. Or they land in just the right spot on the floor to be stepped on during a trip to the bathroom. And don’t get us started about the fragility of their battery case covers; it’s a rare remote in a house with kids whose batteries aren’t held in by strips of packing tape.

But [Alex Rich]’s Bose radio remote discovered another failure mode: imitating a dog chew toy. Rather than fork out $90 for a …read more

Repairs You Can Print: Racing the Clock for a Dishwasher Fix

No matter how mad your 3D printing skills may be, there comes a time when it makes more sense to order a replacement part than print it. For [billchurch], that time was the five-hour window he had to order an OEM part online and have it delivered within two days. The race was on — would he be able to model and print a replacement latch for his dishwasher’s detergent dispenser, or would suffer the ignominy of having to plunk down $30 for a tiny but complicated part?

As you can probably guess, [bill] managed to beat the clock. But …read more

Repairs You Can Print: Broken Glue Gun Triggers Replacement

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

3D Printed Battery Pack Keeps Old Drill Spinning

The greatest enemy of proprietary hardware and components is time. Eventually, that little adapter cable or oddball battery pack isn’t going to be available anymore, and you’re stuck with a device that you can’t use. That’s precisely what happened to [Larry G] when the now antiquated 7.2V NiCd batteries used by his cordless drill became too hard to track down. The drill was still in great shape and worked fine, but he couldn’t power the thing. Rather than toss a working tool, he decided to 3D print his own battery pack.

He could have just swapped new cells into his …read more

3D Print the Blasphemous Helicopter Part Known as a Jesus Nut

Today, when we say “Jesus nut”, we’re not referring to the people who spend their days proselytizing down at the mall. The term, likely spawned in the Vietnam war, refers to the main nut holding the rotors on to the mast of a helicopter which is in the shape of the Christian cross. If the “Jesus nut” was to fail, the rotors would detach from the craft, and there would be little for crews to do except to pray.

[Marius] was presented with a failed Jesus nut, though thankfully from an R/C helicopter, meaning there was no loss of life. …read more

LED Tree Brings Gravity to Christmas

Here’s a fun entry into our coin cell challenge. The power source is the actuating force in [Frank]’s blinky LED Christmas tree, which takes advantage of the physical structure of coin cells and our old pal gravity to roll out some holiday cheer. Talk about forward voltage!

We love the concept, and the circuit couldn’t be more simple. A coin cell is released at the top of the tree and rolls down a series of angled foam board railings covered with 1/4″ copper tape. As the coin cell travels, the negative terminal shimmies along the face of the tree, which …read more

BrewBuddy is a Home Brewer’s Best Friend

Whether coffee, tea, or beer is your jam, brewing is a delicate pas de deux of time and temperature. Proper brewing of any of these beverages can elevate the experience from average to amazing. With this in mind, [Marcelo] created a time and temperature tool to dial in his beer-brewing process.

BrewBuddy is a complex application-specific timer with an integrated thermometer. It lets him program time and temperature profiles for both the mashing process and the boiling process and store up to 10 steps for each. BrewBuddy doesn’t control the brewing temperature, but it does unify temperature-taking and time-marking into …read more
