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?
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.
Well, I don't think we're on the same page. I'm not really into OP's design, but I also don't think that school children use Fiskars scissors. Don't know what's wrong with cat scratchers. Cats love them, and if you use an environmentally friendly glue you can still compost them later. I do have good tools at home, but I trully appreciate your recomendations - that's rather wholesome of you, thanks.
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.
I work with kids with significant disabilities who we keep in public school until they're age 22. They do unskilled jobs and volunteer 'work' and safety is a big concern. If there are five students and one teacher at a table, a plastic device that automatically measures and has a hidden blade is going to be much better for them than scissors or box knives. Yes, we do need to teach children to safely use everyday items and for most kids that's fine, but there are some for whom 'just do it my way' doesn't work. Your life experience may not be the same as that of other people. Teach generally, but make space for the individual.
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.
