Dangerous prints

I just use a 3d printed stick I toss in the wheel. Very effective, although usually only a one time use.

…and usually that translates into a one time (long time) change of the residency address from the current one to the hospital one… :grin:

Reminds me of that stupid kitchen mandolin. I waited years until I came across one on sale. That thing was one of the most expensive kitchen items I ever purchased though because of the hospital bills and medical supplies I needed after using it the first time.

:unamused:

If you wear the helment AND the armor you can ride a motorcycle… probably pop a wheelie even.

If I had a son, I’d name him Wheelie. So one day when he has kids, he’d be Poppa Wheelie!

one could die only once…for the remaining 999 ways, one needs to be resurrected as many times as many ways there are…

Yes - similar to EU standard EN1078 or UK BS EN 1078. This would do nothing for you in a crash or fall scenario.

To pass the BS standard you would need to submit to someone who validates for British Standards Organisation. You cannot just test via an equivalent and declare it to be ā€œcompatible.ā€ BS and EU standards align to keep standards equivalent pre and post Brexit. Same goes for ISO. A third party will usually either take away the product for testing off site, or come to your site to assess whether or not you meet the standards for a service, process or product. I’d find it very hard to believe this was done for the helmet in question.

The ā€œcertificateā€ attached it one from a scientific testing institute in China. This isn’t a BSI cert - quick check under Validation & Verification | BSI shows nothing for various variants on the company name. The ā€œcertificateā€ attached is not a BSI cert, the product has not been tested by a BSI certified tester under their own standards.
Besides the standard isn’t ā€œGB 811-2022ā€ its BS EN 1078 which is same as EU standard 1078. Without that certification this isn’t certified under that standard, and the claim that it meets a GB standard doesn’t ring true.

GB does not stand for Great Brittan, it is ā€œGuobiaoā€ 国标, meaning ā€œnational standardā€ in Chinese. GB 811-2022 is an existing Chinese standard for helmets, and he didn’t claim it met that standard he said it met some parts of that standard.

1995 is not a recent study. 1995 was 30 years ago. Get a grip. PLA is different now. I once drank out of a straw made out of PLA that I printed and i went to the hospital because there was a piece of PLA stuck in my throat. I also got food poisoning and was sick for days.

NO FILAMENT IS FOOD SAFE AND YOU WILL NOT EVER CHANGE MY MIND. Bacteria spreads throughout prints as it travels through your nozzle. PLA is also very fragile and can break off and contaminate your food or drink.

Same thinking applies to prints intended for use in relation with electricity…as clearly demonstrated below…

That’s a pretty poor design for the fork. The handle or the prongs will not fit into the socket. Maybe a steak knife would be a better choice. Best of all, a pair of scissors, you may be able to get a nice spark with those.

Even better is the line that says ā€œperfect for all agesā€ :rofl:
