  • Total agreement.

    Btw: If you want to smooth your prints, get a hot-air soldering station. Set it to 300°C and carefully melt the surface. Then use a flat piece of metal and carefully push it to the molten surface. You have to be careful to only melt the outer perimeter without melting the inner structure, so that the shape stays intact. It smooths much better than sanding while at the same time annealing the plastic and creating a much stronger layer bond.

    And it’s much faster than sanding.

    In general, these hot-air soldering stations are perfect for reworking plastics, not only 3D prints.

    The sauce shelf in my fridge cracked apart due to too many sauces being jammed into it. I used the hot-air soldering station to weld the broken pieces together.

    I paid around €50 for mine, which is a very nice temperature-controlled one that goes up to 480°C. Can only recommend.


  • I got into 3D printing 7 years ago and I design most of the things I print myself, so I know what kind of useful tool it can be.

    The reason I am posting this is because pretty much everyone I know who has a printer and kids prints toys all the time, and any time I’m at any event where someone can shoehorn a box of give-away low-poly-pokemon in, there is one there.

    And all that is plastic waste and nothing else. These things often make a happy-meal-toy look like quality by comparison.




  • The fragile part is easily fixed by changing the print material and/or infill percentage. You’re right on all other points though.

    You can make it clunky, but then it’s not appealing any more. That’s why I said that it’s a trade-off between clunky and not interesting on the one side and fragile and not durable on the other side.

    infill percentage

    Btw, perimeters do a huge amount more for stability than infill.

    3d Printing can lose it’s luster over time if you don’t make the effort of learning 3d CAD software and making new designs. -This is my current struggle as FreeCAD is a painful piece of software to use.

    I’ve been 3D printing since 7 years now, and I mostly design the things I print myself. For functional parts and prototyping, 3D printing is amazing. I am specifically talking about toys here.







  • The bigger issue I see here is that pedestrian access received exactly 0 minutes thought when this road was built, even though there’s clearly enough foot traffic to form a desire path on the patch of grass on the left side of the picture. That doesn’t happen without foot traffic, but not only is there no pedestrian crossing of any kind, but there isn’t a foot path on the island on the left, even though there’s a footpath leading up to it that just ends without anything to connect to.

    What do they think people would walk there for? To just stop at the intersection and turn back?





  • Listing already exists, but in practice it’s quite impractical, mainly because it’s either not granular enough or too granular.

    If the listing feature allows me to allow/deny on a domain basis, then allowing Wikipedia for example would mean that I’d also allow all the non-child-friendly content on there too. Like the literal full-length porn videos or the photographies of genital torture that are on there. And if I block all of Wikipedia, I also block all of the hundreds of thousands of informative and totally child-acceptable pages on there.

    If, on the other hand, I allow/deny on a per-page basis, then using the internet becomes nigh unmanageable, because each click of my kid requires me to allow/deny the next page. It’s not that often when using the internet that you access the same exact url every day without clicking to sub-pages.

    A header would solve that issue. That way I could e.g. allow all Wikipedia articles that are rated for ages 6 and that’s ok. The rating should of course be like for movies, so that it doesn’t mean that a child would understand the articles, but that there’s nothing child-endangering in there like the videos and images (and accompanying texts) mentioned above.




  • The solution to all of this “think of the children” stuff is that devices owned/used by children should have to be registered as a child’s device, which would enable certain content blockers.

    That’s kinda the case right now already, but the problem is that adult-only sites don’t work with that currently.

    So the right solution would be to mandate that e.g. all sites are required to return a header with an age recommendation or something similar, so that a device set to child-mode then can block all these sites. And if a site doesn’t set the header, it will also get blocked on child-mode devices

    Wouldn’t be too hard to do, and accidental overblocking would only occur on child-mode devices, so there’s not much of a loss there.

    Legislation could then be focussed on mandating that these headers aren’t falsely set (e.g. a porn site setting the header to child-friendly).
