I designed a cardboard cutter that turns boxes into free cat scratchers
I have an AnkerMake M5 and it’s gloriously painless. There are intrinsic unavoidable challenges to 3D printing, but this thing has been incredible for casual creation.
I’m not the OP but I went ahead and bought his file and sliced* it and with 20% infill, it will require about 77g of filament. So with one normal spool, you could print 12 of them.
I can only vouch directly for the M5, but looking into the differences, it looks like the M5C would be a solid option. I would miss the onboard camera and the ability to check my prints and get notifications of suspicious issues, but the printer itself is more or less the same otherwise.
Ender 3 is pretty good introductory model and does nice prints with little effort.
If you’re a buy once, cry once sort of person, Prusa makes good stuff that has a lot of community support.
Don't get an ender unless you want your hobby to be working on the printer. That's fine, but it's not the same as having something ready to go when you unbox it.
Prusa printers are quality and open source; very much worth supporting if you have the money. Your hobby will be printing things for other things if you get one.
Bambu printers are cheap, but not open source. However, you will spend most of your time actually making stuff instead of fixing the printer.
Cheap, reliable, open source/modifiable. Pick two.
I own an Ender 3, 5, and a Prusa Mini. The mini is by far my most reliable printer, but both enders have had a lot of work done to them to get them where they are… and not quite click to print yet.
At one of my jobs I maintained some 35 Prusa Mk3s, about a dozen Elegoo’s, and witnessed their graveyard of Anycubics and some other brands. The Prusa’s generally only needed to be unclogged or have their nozzle changed less than once a month, with only a couple failures per week max, the room also was not temperature controlled and they had some… questionable engineering practices.
The elego’s were like pulling teeth, needing glue to keep it adhered, frequent clogs and skips, thermistors needing replacement after under 100 print hours, blobbing would get into the part coolig fans. Small leveling knobs. Prusa’s IMO were designed to be serviceable, but seem to need it way less.
Especially at a business, the premium on Prusa printers over say bambu labs is well worth their customer support. Ive never used a Bambu so I cant necessarily recommended or not, and I do wish I had an MMU on the cheap as you’d get with their mini, but Im most pleased with my Prusa mini
A lot of libraries offer 3D printing for about the cost of materials.
It’s worth trying out before dropping huge cash if it’s possible near you.
You’ve designed a niche solution to a problem that doesn’t exist.
Use a box knife. Or, for a more versatile tool, get a Morakniv Companion.
If I don’t design and print something I could buy I might be tempted to do more mods for my printer.
Things like this give us… balance. Luckily I have a new project… building a Voron so it’s both something new AND printing printer parts.

Otherwise known as, “Justification for ownership of printer.”
Look, I totally didn’t just buy this thing as a hobby to make more parts for itself! See, I actually do occasionally make useful things with it!!!
That’s what I tell myself, anyway…
Exactly… this printer is useful honey.
I can make parts for the printer, accessories for filament management for the printer.
Halloween decorations… once I get the printer back online when I have this mod finished.
Parts for another printer.
Mounts for the brooms… when more filament comes in since I used the last of it for the parts for the new printer.
Save 450 on a unique appliance part they’re not making anymore which now justifies the thousands I’ve spent on this thing.
Seriously though. It is a fun hobby and if you want to just print and make things and not tinker there are plenty of good options out there. Me? I like tinkering. It’s a blast.
I mean that’s kinda the whole deal with 3d printing, it’s useful for really niche applications where you can just add a small amount of convenience to your life.
Someone else commented about this being good for school kids so they can safely make cat scratchers to donate to animal shelters, and as a cat owner with a constant pile of recycling I can see this being actually useful if I wanna avoid spending $20-$40 on one of those fancier cardboard cat scratchers from Target or whatever.

Is it? All I ever request to be printed is the proprietary part that prematurely broke as it was designed to do.

Instead of teaching them to use scissors? We’re raising a generation that can’t think or do for themselves. They’re reliant upon consumption.

As an adult you think it’s more useful than a box knife? It’s not even going to be faster than a box knife with straight edge. And, why do you need a product to pet your cat?
Boomer posting
“Kids today!!!”
You don’t have to be a Boomer to be boomer posting.
“Kids today” is an illustrative phrase, not a literal one.
People have been interested in new gadgets for all of human history, no matter the cost or utility. Acting like something changed is boomer posting.
People have been interested in useless gadgets since capitalism has mandated perpetual increase in consumption. It’s now so bad that the solution to all problems is needless consumption.
But, neolibs gonna’ neolib until they can’t afford their filament.
Cutting carboard with scissors? It can be done, but it’s a chore amd the results are poor. I wouldn’t wish it on school children.
Your tools probably suck.
Any knife and straight edge is faster and easier. Any warehouse worker knows this. Any compost bin is better than cat scratchers. Any environmentalist knows this.
For scissors I recommend Fiskars titanium nitride. Just yesterday they gave me a nice curve in 1/16th aluminum. Cardboard cuts like a hot knife through butter. And, I bet they cost less than the materials used in the tool in the OP.
Box knife reco: any metal housing without an auto-retract safety feature but with a retractable blade
Knife reco: Morakniv Companion: cheap, sharp, extremely versatile.
Aviation snips reco: Klein J1102S will take 12" cheater bars and be fine
Fence: use a metal level instead of a metal ruler to prevent mistakes
Learn how to make a jig for speed and accuracy in any repetive cutting task.
For adults: box knife with a jig consisting of a fence and stop block
For children: auto-retract safety knife and add a second fence to keep the blade enclosed
A child learns nothing but dependance on stupid gadgets from the device in the OP.
That’s great. Use this thing. It’s what I’d give my developmentally disabled 55 year old uncle as well.
But, it’s definitely not what I’d teach my child or the vast majority of other children. A typical child only needs a couple of safety accommodations relative an adult: an auto-reteact safety knife and a double fence.
make a jig
You mean like the handheld jig seen in the demo?
I meant without printing anything, for anyone without access to a 3D printer. This was in response to the above comment about freehanding it.
To use an ordinary box cutter for this purpose all you need is something to use as an endstop and something to use as a fence, and they have to be parallel to each other.
Hard disagree.
Honestly, my bigger gripe with the video is the little dots of hot glue. That feels like wouldn’t hold up (I’ve had cats disassemble store bought scratchers). I’d brush on flour paste or thinned down school glue for non-toxic full coverage. You could even mix in cat nip to encourage use.
I don’t like what you’ve said so you’re a troll. We don’t serve your kind around here.
SMRT.
I found this one online from last year
