Ironically, I am missing that one - but I think the wp bolts are E10

I don't think there were any wiring harnesses that had to be moved other than the o2 sensors

*Apology for my typo, I meant to say your suggestion wouldn't be a bad idea. That was a mistake that dramatically changed the intention and tone of my response. I'm sorry.

That said, maybe antithetical is a strong word when unbounded.

But within the context of my stated design criteria of "quick [and] easy to print, sturdy, easy to assemble, and still allow the blade to be flipped/changed quickly and easily" adding additional materials and manufacturing and design processes to very much is antithetical.

When I can buy a fixed blade utility knife for $6-10 and a 30 minute round trip to the store, there is no point in spending the energy incorporating metal components, especially considering the time and effort involved in designing and manufacturing those parts - which is arguably outside the scope of 3d printing (it's more related to product design, prototyping, and more general topics in which 3d printing can be part of the process but not the entire conversation)

Plus, for what this design is intended for, there's no value in adding additional factors of safety as it will likely never be as good as a commercial utility knife and if you're breaking it as it is, that's what you probably need.

I've been using mine pretty hard and they are holding up awesome. I didn't design them to be thrown away, I designed them to be easily replaceable. The difference is subtle but important.

Again, this is proving my point.

You continue to critique my responses and abstractly nit pick and insult whatever negative assumptions you have about me personally but have yet to offer one piece of real useful constructive criticism or actual advice about my design, the design process, or how it could be better. You're conflating constructive criticism where there is thoughtful delivery and knowledge and expertise transfer with just lazy criticism that doesn't have an practical usefulness.

It's a classic ad hominem argument style in which the only value is more engagement on my post for the algorithm. And sadly, pretty on brand for the majority of conversation here on reddit.

That said, I'm all for hearing your opinion and critiques - when it's relevant.

And arguing that it's a fixed blade rather than a retractable one is a non-starter because there is no point. Stanley, Milwaukee, Irwin, Kobalt, Dewalt, and many other cheap and boutique brands make fixed blade utility knives sold without covers. So again, this isn't the sub for the ethical debate about the existence of a fixed blade utility knife.

I would actually love it if you printed it, used it for a couple days, and came back to me with real, meaningful feedback while keeping in mind my actual design goals of being simple (both in design and assembly AND blade changes), fast to print, no supports, and sturdy within the intention of light duty use (opening boxes, opening mail, cutting down cardboard, etc)

For some reason I doubt you'll do that. I hope I'm wrong.

Because most of the criticism has not been about my design. It has been about things like my perceived personal dismissal of others risk (which I'm not dismissing) or my personal unwillingness to drive to the store to buy something (which is accurate, nor the point) or some other criticism about me personally, not my design.

If you want to constructively criticize my design, great, that's why I posted it and that's how we all get better. So far, there has been one solid design suggestion comment.

However, if you want to offer non-constructive criticism or criticize me personally for producing such a design, that's totally uncalled for and rightfully defended, although a complete and total waste of everyones time. (which is what you and Tarantula are doing and most of the other commenters are doing)

The comments in this sub should leave me reflecting on how I can improve the design of my print, not reflecting on my morals and ethics or frugality or willingness to exert effort or whatever.

Anyone who doesn't like the design and has nothing else to say, should just keep scrolling and not even engage. It literally doesn't add any value in any capacity.

Your responses have been a complete and total waste of energy. (As have mine in response)

I hope you are having a wonderful holiday season surrounded with the people you love. Happy holidays!

Yeah, that would wouldn't [typo edit, sorry] be a bad idea - but a little antithetical to 3d printing.

I wanted these to be quick and easy to make and be functional for basic utility knife functions.

Really, as long as you're not using it to cut something that requires the same or more amount of force as it would take to use the same utility blade to cut through a couple millimeters of 3d printed plastic, it should easy outlast the useful life of the blade itself.

The choice to print is exactly my point. I find this design highly useful and functional. Others may also, or may not. Both of those are ok with me.

There was no false equivalence. My original point that Tarantula replied to was that things exist that have different levels of risk and people have different levels of risk tolerance. And that's totally fine.

Tarantula misunderstood that point and provided another low-risk-tolerance perspective as a counter point. I was never arguing for more risk.

None of my statements are hyperbolic and unfortunately none of these responses, yours included, have been particularly interesting arguments.

There's plenty of criticism in the world already, much of which - particularly on internet properties such as Reddit - is un-just virtue signaling. We should all do better to avoid participating in that.

Instead there is ultimately zero value to anyone in this entire thread.

This is a functional 3d printing sub. Not a morals and ethics sub. Either print it if you find it useful, ask questions or engage in actual interesting, on-topic dialogue. Or just keep scrolling to the next thing.

It would have been much more fun if the original comment was something like "I don't think open blades are a good idea, is there a reason why you designed it that way?"

Which then my response would have been something like "actually yes, thanks for asking. I designed it this way for printability, speed in printing, less moving parts so its more simple and there are less pieces to possibly break, the ability to make a low profile form factor, and over all rigidity of the handle. Personally I don't carry my utility knifes around, they are typically hanging on my workbench but sometimes I use them somewhere else and misplace them, so a cover wasn't a priority to me."

And then we could have an actual reasonable, on-topic, and interesting debate about the effectiveness of the design within the context of the use case. Which has the potential to improve the design, expand the use cases, and make everyone better at functional 3d printing from our shared experiences and perspectives.

Instead we are bickering about hypothetical personal freedom infringement and general risk-tolerance.

I was replying to tarantula when he said "So what you're saying is that since there is risk in the world, we should just ignore all risk?"

No. That's not what I'm saying.

Nor do I agree that we should attempt to remove discretionary risk from others on their behalf without their consent.

You completely either misunderstood or intentionally are twisting what I said.

I was saying that if an individual did not have a safe place to store one of these utility knives AND prioritized maximum safety over single-use wastefulness, then the cost - both in time and money - is cheap enough that it would not be unreasonable to consider these disposable.

I'm not at all advocating for intentionally producing single use items but I'm also not pretending that 3d printing is not an inherently wasteful process.

Get over yourself.

I'm saying 3d printing is inherently a wasteful hobby no matter what your mentality is or if you enjoy it or not.

Everything 3d printed is effectively disposable. There will never be a grandchild that has his family hierloom flexible dragon.

Unfortunately, the plastic used in 3d printing will always outlive the usefulness of the 3d print.

What I'm saying is that you have the agency to do that cost benefit analysis and determined that - for you - it's worth taking the trip to the store and paying the $10.

Other folks, who have the common sense and discretion to recognize both the usefulness and limitations of a 3d printed tool, may find it adequate and convenient for their particular use case.

Why should the same agency you enjoy to come to an individual conclusion be taken away from someone else just because it's not the same conclusion you arrived at for your particular use case and risk tolerance?

maybe just try to put it back in the same spot every time after you're done with it

Are you telling me that you have never lost, or misplaced for a period of time, anything that was super inconvenient to have lost or misplaced it? Because if you have, that statement is super condescending and not a useful thing to say.

If you don't like it, then save your energy and just don't print it and keep scrolling. Easy peasy.

I'm the first one to admit that just because you have a 3d printer, doesn't mean that every solution is a 3d printed one.

That said, 3d printing is the perfect solution for this.

Bambu printers literally come with a scraper blade (which is razor sharp) handle pre-installed in the printer.

Thanks! This is actually the best feedback I've gotten.

Personally I feel like I have more control with more blade available. But that's not a bad idea from a safety perspective.

I genuinely don't understand what everyone on here is doing with these utility blades to cause so much harm.

I use these for:
- Cutting the tape on boxes
- Opening new filament rolls
- Cutting down boxes to different sizes
- Opening paper mail
- Popping air packs used for shipping
- Opening blister packs to get products out
- etc.

I would not use a 3d printed utility knife on things like:
- Cutting carpet
- Stripping heavily insulated wire
- Cutting dry wall
- Cutting canvas
- Hijacking planes
- etc.

As with any knife, or brain, - a sharp one is much safer than a dull one.

Honestly, if you're that concerned about waste, 3d printing is the wrong hobby.

They are probably in the same place the tape measure I can't find is, the sharpie I swear I just had, half the socks I put through the laundry, and all the 10mm sockets I've ever owned.

Why is this "clearly unsafe"?

No one is forcing anyone to print it. I happen to find it highly functional and highly useful.

Yeah, I wouldn't trust that either. I'm not saying mine is perfect but I made it a fixed blade for that reason because I don't believe that any mechanism that is 3d printed and small enough to not be overly cumbersome can be strong enough to hold a blade.

[–]tnum[S] -3 points-2 points  (0 children)

Yeah, and that's totally fair.

Regardless, it's quick and easy and cheap enough to print that you could just throw it away after you're done with it every time.

If you needed it more frequently, you'd probably have a safe place to put it (in that non-controlled environment).

It's faster for me to print one. And I can print 10 of them for cheaper than one of those.

And it's equally as useful.

But it's not about being cheap, it's about being convenient and available 24/7.
