I have an FLSUN T1 Pro — a delta-style 3D printer I bought on Kickstarter about five years ago. It doesn't have multiple extruders, auto material switching, or any of the bells and whistles the new crop of printers come with. But it was fast for its time (delta printers are inherently quick), and it has served me well with minimal maintenance. I print a fair amount of stuff on it, but I'm not running a business — this is for my own use. Someday I'll upgrade to something fancier, but for practical household items this thing has been a fantastic investment.
I don't print benchies, stormtrooper helmets, or articulated dragons. What I do print are things that solve real household problems — and the ones that survive get used every single day. Here are the five that have earned their spot.
1. Flanged 2x4 Post Base Mounts — Garage Ceiling Storage
I wanted to build a drop-down storage area on my garage ceiling to reclaim some floor space. I found some flanged 2x4 post base brackets that gave me the idea, and I designed my own version with custom mounts for joining the 2x4 boards together — the kind of connector you just can't buy off the shelf. The brackets alone technically could hold the boards in place, but it wouldn't have been safe. The mounts I designed had pre-placed holes so I could add screws and secure everything properly. Plus it looks nice on the finished structure — which matters more than I expected when I wrote about building out my home lab setup — which matters more than I expected.
2. Toilet Paper Holder
This is one of those things where the replacement part costs almost as much as the original fixture. I designed and printed a simple toilet paper holder that's been hanging on the same wall for over a year with no issues. Cost in filament was maybe $0.40. The nearest store-bought equivalent starts at $8. It doesn't look like a factory part, but it holds the roll and nobody has complained.
3. Custom Brackets and Hooks for Every Room
This is less one item and more a category that keeps expanding. I've designed and printed all kinds of brackets and hooks — for laundry room racks, garage walls to hang outdoor tools, you name it. Basically, if you need a hook to hang something, you can most likely print it. I've made custom-fit hooks for everything from extension cords to garden shears. The design takes maybe 10 minutes in CAD, the print takes an hour, and it works better — the same kind of satisfying fix as the bumper spacer I printed for my Ecovacs Goat 1000 robot mower than a generic hook from the hardware store because it was designed for exactly what I'm hanging.
4. A Remote Holder for the Couch
I designed a wall-mounted remote holder that attaches to the side of my couch end table with a screw mount. It holds my NVIDIA Shield remote, my Dreo fan remote, my Sennheiser headphones, and a few other odds and ends. Everything has a dedicated slot so I'm not digging between couch cushions anymore. It's one of those prints that feels trivial until you realize how often you reach for it. I measured each remote with calipers, designed the slots with a little extra clearance, and it came out perfect on the first try.
5. Dog Bowl Risers for Our Senior Pugs
We have two senior pugs, and raising their food bowls makes eating more comfortable for them. I didn't buy bowl risers — I just used a little filament and printed a pair on Tinkercad. The design is simple: measure the bowl you already own, then make a hollow 3D cone shape with a flat base. It takes about 15 minutes to design at Tinkercad.com and the print uses almost no filament. You can make them for any size dog — just measure the bowl, make a cone, and you're done. Comparison bowls on Amazon run $15-25 a pair. The filament cost? Maybe $0.75 — cheaper than the time I 3D printed a NAS caddy insert for my Jellyfin media server setup. And it's a great project for teaching someone who's never used CAD how easy it can be — Tinkercad is free and genuinely user-friendly.
What I've Learned After Five Years With This Printer
- PLA is fine for most indoor stuff, PETG for anything that gets warm or wet: PLA degrades in UV and heat. I use PETG for garage storage projects and anything that might end up near a window.
- Delta printers are underrated for practical parts: The tall, cylindrical build volume of the FLSUN T1 Pro is great for functional prints. You're not printing action figures — you're printing brackets, mounts, and holders that fit in a column shape perfectly.
- Tinkercad is genuinely free and genuinely easy: I started with FreeCAD but Tinkercad is what I actually use for quick household fixes. If you can drag and drop shapes, you can design a usable bracket in 10 minutes.
- Calibrate once and forget it: I spent a weekend dialing in e-steps, temperature, and retraction about four years ago. I haven't touched the settings since. A calibrated printer is a happy printer, and maintenance has been minimal.
Frequently Asked Questions About 3D Printing Household Fixes
Can I really save money 3D printing household repairs?
Yes. Every print I described cost $0.40 to $2.00 in filament. The store-bought equivalents would have been $8 to $30 each. Over the five items here, I saved roughly $75-100 — more than enough to pay for a spool of filament and then some. The real savings come when you fix something you'd otherwise replace entirely.
What type of 3D printer should a beginner buy in 2026?
That's a bigger question than a single answer. Bambu Lab printers are the most popular recommendation right now — they work out of the box with minimal tinkering. But there are reasons to consider other brands depending on your budget and what you want to print. I'll be covering this in detail in a future post, so check back for the full breakdown. The key takeaway: do your research before buying, and avoid used printers if you're a beginner — troubleshooting a broken printer is not how you want to learn the hobby.
Do I need to know CAD to print household fixes?
Not really. For simple parts like brackets, risers, and holders, Tinkercad is free and genuinely beginner-friendly — you drag and drop shapes, combine them, and export an STL file in minutes. I designed the dog bowl risers in about 15 minutes and I'm not a designer. For anything more complex, there are thousands of free models on Printables and Thingiverse that you can download and print immediately.
What filament should I use for household items?
PLA is fine for most indoor prints that won't see heat or sunlight. For garage storage, kitchen items, or anything outdoors, use PETG — it handles UV and warmth better. For parts that need to flex (like the mower bumper spacer I mentioned), TPU is the right choice. A spool of each costs about $20-25 and will last you dozens of prints.
Is 3D printed food contact safe?
Generally no, unless you use food-safe filaments and a dedicated nozzle. My dog bowl risers don't contact food directly — they just raise the bowl off the floor. If you're printing things that touch food, look for food-grade PETG and use a separate nozzle that hasn't printed anything else.
If your 3D printer is collecting dust, try fixing one broken thing around the house this weekend. It doesn't matter if it looks ugly — the feeling of not having to buy a replacement is addictive.
If you don't own a printer yet and are thinking about getting into it, do your research first. There's a lot out there and a lot to know before you purchase. Most people these days are very happy with their Bambu Lab printers and they probably serve most users well, but there are still reasons you might not want to go with Bambu Labs. I wouldn't recommend a used printer for someone just getting started — if it needs something fixed, it's going to be a struggle for a new user. I'll be doing a deeper dive on 3D printers in a future post, so stay tuned for that.
