While you can stick to just making the 3D printing projects that everyone always talks about, like Gridfinity, a Flexy Rex, or other toys, there are a lot of projects to do that nobody ever highlights. Here are five 3D printing projects that I think are fantastic and deserve way more attention than they get.
Battery holders for weird sized batteries
Where else can you find an 18650 or CR2032 holder?
Something that I absolutely love that I 3D printed was holders for the various batteries I have at my house. Of course, I have AA, AAA, D, and C, but I also have 18650, CR2032, and a few other different-sized batteries.
It’s easy to find holders for the common sizes, but the uncommon ones? It’s nearly impossible. Take an AAAA battery as an example. Where can you find a battery holder for such an odd battery size? Really, only with 3D printing.
With 3D printing, it’s easy to either find an already existing model for the batteries you need to hold or simply make your own. I couldn’t find a battery holder out there that I liked for C/D batteries, so I opened up my favorite CAD (computer-aided design) software, drew some circles, and printed a holder.
Dispensers or holders for everything
Having a zip tie holder is nicer than you think
While it’s easy to find generic containers or holders to use in your workshop, having specifically-sized holders is actually extremely nice. Consider that container of zip ties under your toolbox.
Growing up, my dad had a tall container that had every size of zip tie he owned in it. Each size was rubber banded together as an organization method. This worked, but it would have been so much tidier to have a 3D printed organizer that kept each size separate and easy to grab without having to deal with that rubber band.
There are many things just like zip ties you can organize in your shop too. Sanding discs, painter’s tape, towels, gloves, and so much more. With 3D printing, chances are you’ll be able to find a model for whatever you want to organize without much trouble, print it, and enjoy the organized life.
Fixing appliances in your house
Sure, you could buy the OEM part online and wait a week for delivery, but why?
It’s crazy to think of how much money OEMs (original equipment manufacturers) charge for some replacement parts. I’ve seen small pieces of plastic that cost $30, $40, or even over $100 in the past when working on fixing an appliance around my home.
With 3D printing and a little know-how, you can easily fix a lot of appliance issues yourself. If it’s a popular appliance, there’s a good chance someone else has already designed whatever you need, too.
3D printing appliance repair parts is also about more than just saving money. I’ve needed parts for my appliances before and had to wait several days, if not over a week, for it to arrive, because only one place sold it and they shipped them on the back of turtles (or so it felt).
With 3D printing, even if you have to design it yourself, it can often only take a few hours from inception to having the finished product ready. Even if it takes a day or two to design it, it’s still often faster than waiting for the part to get shipped to you—and it most certainly will cost a lot less.
Board game organizers
Stop using plastic bags and 3D print proper organizers already
I married into a board game family, and I don’t mean Monopoly and Clue. These board games have hundreds of pieces, and everyone has their own stash of those pieces.
There’s so much that goes into a lot of these board games, and they often don’t ship with proper packaging for the small pieces. Most of the time, they ship with either zip-top bags or little plastic containers without a lid.
Using 3D printing, it’s very easy to find organizers for most big board games out there that are already made—or even make your own board game from scratch. All you have to do is a little searching and then, when you find a model, print it.
I’ve not fully optimized our board game storage yet, but it’s on my list of things to do, and I definitely think that not enough people talk about that.
Under desk mounts for everything
Why have your laptop or dock on your desk when you can just mount them underneath?
I recently completely overhauled my desk setup. I didn’t get a new desk, monitors, speakers, or any of that. I simply took my MacBook Pro that used to sit on my desk and mounted it under my desk. After that, I took my Thunderbolt 5 dock that was on my desk and mounted it under the desk, too.
I designed my Thunderbolt 5 mount because I couldn’t find one for my specific dock. However, I found a MacBook Pro mount that worked perfectly for my needs already designed. All I had to do was print it and screw it to the underside of my desk.
Now, I’m thinking of other things I can mount up and out of the way. I have most of my desk cleared off, but I still have a Stream Deck sitting on the desk which isn’t used all that often. I’m considering mounting that underneath the desk next, because that would definitely make for a cleaner setup.

It features up to 20-color printing with the AMS unit, has an upgraded built-in camera for remote monitoring and time lapses, and has an enclosed body for printing even high-temperature filament.
Don’t get boxed into just making Gridfinity bins or toys with your 3D printer
If you’re anything like me, then there’s a good chance you might be thinking “I have nothing to 3D print” because you’ve already organized your drawers and made some fun toys. While those things are great for 3D printers in general, that’s not all your 3D printer is capable of.
I’m constantly amazed at what my 3D printer is capable of making. In fact, I’m about to start a personal challenge where I will try to find something useful to 3D print every single day for a month. If you’ve never done a challenge like that, then you should. It’s a fun way to get outside your comfort zone and find new uses for the tools you already own.
