I printed new treads for my beach cart in TPU.
The single most useful print is just a simple cylinder to repair a broken knob on a nearly brand new kitchen stove. A new knob cost $35 at the time and had a 2 month lead time from the factory, (it was during the covid lock down).
It took longer to turn on my computer and start up my CAD program than it did to design the repair part for the knob. 30 minutes later, I had the sleeve printed and super glued over the broken part and the knob reinstalled on the stove.
That’s been 7 years ago, the repaired knob is still there and in use daily. And one more knob got the same treatment. It probably took less than 10 cents of PLA and electricity for both repairs.
Drops for drones, drone parts.
New interior door handle for a john deere 450clc excavator. Red pla, so far, has outlasted the original
With the exception of crap for the kids and cake toppers, everything I print is to solve a problem I/we have.
Here are the gridfinity drawers I designed and printed for under my desk. https://www.printables.com/model/1129785-gridfinity-under-desk-drawer-system
I’m about to start printing triple stacks of these to put better drawers into my IKEA KALLAX shelves than the ones IKEA sells.
A AAA-battery to AA-adapter. I randomly had 50 of the smaller ones lying around, so it really came in handy.
Can’t share a link, but there should be dozens of this kind of model on any site. “Can’t”, because the model I grabbed was definitely among the worse ones.
Not sure it’s the most useful in a day to day sense, but was great for a d&day darksun campaign. I have got quite a few grom gloomykidminis, great quality
Most useful as in something I wouldn’t have otherwise is probably some gridfinite thing. SD and usb stick holders maybe.
Most used is probably a plain headphone hook for office. Daily use and storage for years.
Most saved time and money? Jigs and dummy parts at work which have helped avoid more expensive processes and mistakes in more expensive processes.
Earbud Charger Charger. Put your earbuds in the charger and put the charger in the charger charger and the charger charger keeps the charger charged.
In other words, an earbud case holder. The earbud case can charge wirelessly so I put a wireless charge coil behind where the case sits. I put a piece of metal on the back of it so it sticks to a magnet mount in my vehicle but I plan to 3D print part of my dash with this built into it.
But what charges the charger charger?
The vehicle. If the case goes dead you simply buy a vehicle, drive around until charged, then you can sell the vehicle or push it off a cliff or whatever
I printed bushings for the augers we have on the bottoms of a couple grain bins. They’ve lasted for about 10 years in ABS, and the old ones were ridiculously expensive to replace even though they were just made of maple. Probably run a couple of million bushels of grain through those augers since I replaced them.
I also replace the impellers in a couple of pumps we use to pump river water up to cattle, and the design I cribbed is probably twice as effective as the originals, making it more efficient for the solar panels we use to power them.
I’ve replaced various implement parts around the farm with other prints, things like parts for our seeder and sprayer.
Most useful was probably this holder for two 1/2in PEX pipes. Printed in ABS, it holds cold and hot pipes in parallel, and uses a #8 screw for attachment. All commercially available holders are for a single pipe, and use nails. Hammering nails in tight spaces (and doing so twice) is not particularly convenient for me, thus, this contraption was born.
Other than that, stuff that is so practical it is easily forgettable: wall mount for a garage door opener, Y splitter for an exhause fan, various covers and containers.
Probably most useful is Gridfinity for the desk drawers and multiboard for the wall. Not completely sold on multiboard yet - there are so many pieces and options that I haven’t got my head around it yet.
I printed my credit card wallet which has been ace.
I really want the stagetop table system to be useful, but I struggle with the print times and volume of parts to print and might wait until I have a faster printer.
Some light fixtures using rbgw- including one that has a “secret” party mode. (It’s for my niece and it has a Stary Night, but with unicorns, screen.)
Various shelving, and such.
Probably the most stand out thing, though is a robotic snow sweeper. It’s very bespoke so I won’t be publishing it, but it goes out and clears my driveway whenever it snows. The chassis, wheels and sealed housing were all printed, as well as fairings to reduce snowy build up.
It doesn’t matter how bespoke. You should publish it!
Dude. We are about to sell our home because clearing snow off our long, steep driveway is a massive pain. It has taken years off our lives. We were seriously looking into snow removal robot but inflation and tariffs put that way outside our price range. You might be underestimating a potentially huge market. I would’ve never thought that’s something that could be DIY’d!
I have one of those twelve foot tall skeletons for Halloween and the joints are pretty fragile resin for the weight, luckily they are replaceable and there is a pretty strong DIY community for them and you can download free replacement parts.
Every Halloween I take inventory of what needs replaced, print it, and it’s set for another year.

I’ve found an infinitival copula deletion!
My washing machine broke. Wouldn’t drain. I took it apart and realized it was going to be a huge pain to fix if I didn’t drain it first, but it wouldn’t drain on its own. So I designed and printed an adapter that would let me run the pump that drains the washer from my cordless drill. PLA isn’t the strongest material, so I went through like 3 of them draining the washer, but it worked fantastically. Very simple to design and a quick print. Big payoff.
Aside from that, wall mounts for my Nintendo Switch and accessories as well as a wall mount for my NAS solution, a shield for the face of my alarm clock so it didn’t shine bright digital-clock LED light in my face all night (but I could move it aside and check the time), mounts for SAD lamps in convenient places. Most of what I print is custom-designed stuff for utilitarian purposes.
Wall mount for a Switch, you say?
So, the one I used appears to have been removed from Thingiverse in the meantime, but I’m pretty sure it was V1 of this (which has been remixed a couple of times by someone else and is up to V3). It is a very tight fit, though. (Like maybe the original designer left zero tolerance.) If I had it to do again, I’d go for a different one, but I’d guess probably V2 and V3 have resolved the way-too-tight fit issue.
I made a couple of things myself for mounting my Joycon charger on the wall. (Definitely improvements that could be made to the wall mount one. Conical holes for the screw holes for one. But it does the job.)
Outstanding, thanks for the visual aid 😀
