STL files available on Thangs
This would work with regular shaped blades, right? Like this? https://www.amazon.com/gp/product/B01GIZ9164/
Yes any standard sized utility knife blades should fit. I tested a bunch of different brands from my local hardware store.
FYI those are stupid expensive. Your can get 50-75 for that price at your local hardware store.

I found this one online from last year
https://www.printables.com/model/356486-cat-scratcher-cardboard-cutter-v2
Looks like the specific design in this video is being sold here, but if you'd prefer something that isn't behind a pay wall there's a few options (like this one).
Side rant: I'm all for people getting compensation for creative work but I feel like it's wrong to put the source file behind a waywall instead of simply selling the actual print directly to people that don't have access to a printer, that seems much more fair imo
Selling the actual print is more work than selling the STL.
Oh definitely, I just think it's easier to justify paying for a physical product than it is paying for a single file if you still need to manufacture it yourself. Still a valid business practice, I'm just biased toward "information should be free" and all that.
It's $3 which is well worth the time saved by not having to design it from scratch.
Someone had to use their skills to create it, do you think they should work for free?
I don't disagree, never said people should work for free. I recognize there's a disjoint in believing good information should be free[ly accessible] and also that people deserve compensation for work, though. It's just one of those contradictions I haven't solved as far as my own beliefs.
More than anything I was complaining, like I said it's a totally valid business choice, I'm just a penny-pincher lol.

But it's not just information, someone sat in front of their computer and put the work in to design it, then print it and iterate.
You're paying for that process, and for the time and effort the person took to acquire the necessary skills.
However, there should be a noticeable price difference due to the easy scaling / replicatibility when distributing digital goods.
I'm with you insofar as the final product feels like it should be 3 bucks, not the file.

I mean, buying things like clothes patterns and carpentry plans is definitely a thing. An stl is really no different.

I tried to buy the model from an artist recently for personal use(friend wanted some Mickey ears of a specific style). Person told me no and quoted me $130 with a 3 week wait time for a physical product that was something I could print in about an hour myself. For a Disney product they were already infringing on themselves.
Went elsewhere and found someone selling the model for $7. Figured that was fair for the effort to transform it into a model file.
Turned out I was wrong - only took me 20 minutes to print.
Some of these artists are ridiculous....

Awesome! Is that a real device that's available for sale? Those would be good school or scout projects to donate to animal shelters.
I have the STL files on Thangs for 3D printing.
I've been thinking about getting a 3D printer. Well, yesterday I decided I need a 3D printer. I know nothing at all. What should I get?
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 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 have a 3D printer buyer's guide on my website that lists a few. I mostly use and would recommend any Bambu printer, there's a few that can suit any price range. Elegoo also make good printers too which won't break the bank

I have used something like that. The blade dulls pretty quickly and it is a lot of work. I got 2 or 3 usable cat scratchers out of one blade.
Given that one cat scratcher cost something like 2,50€, it simply wasnt worth it for me.

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.
Welcome to the world of 3d printing
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.
Things like this give us… balance.
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...

Good luck getting consistent cuts while you're freehanding. The idea is to make the nice flat cat scratching pad, and also being able to make the tool with the tool printer you have at home
I mean, you could make a jig to use a box cutter to make consistent width strips very easily with three pieces of scrap wood. But this commenter coming in here for the express purpose of trying to shit on 3D printer hobbyists was a stupid move on his part.
Or a ruler. And make the strips the width of the ruler. The only "extra" needed is a cutting surface. This plastic gizmo simply eliminates the need for a work surface, nothing else.
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.

Hard disagree.
- Waste packaging is a common problem.
- Lots of folks have cats
- You can already buy a commercially made strip and strap cutter. This is just fixed size version that uses a more common blade.
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.

It's essentially just a jig to use regular utility blades to quickly cut strips of equal width.

Is the hot glue pretty good for standing up to kitty abuse? I was thinking PVA glue, but a glue gun would make things quicker.
My two are pretty good with not eating things they shouldn't so I just made sure stringy bits were cleaned up. Googling says PVA/wood glue is safer for cats but I would check brands if they are non-toxic

That looks a lot easier than gluing a stack of boxes together and cutting off slabs with a bandsaw like I was planning.
I guess this is my excuse to finally finish calibrating my new extruder setup.
I love this! Free cat scratchers might not seem like they have much value, but has anyone seen the price of those ready-made things?! They're pushing $20 for a large-ish flat scratcher at lower volume places like TSC, but Target isn't much better, still $10 for a 10" x 18" flat cheapy.
Down with bougie cat cardboard!!!
