    At some point the toys would fail, they were 8 and 9 year olds after all, but it could take a month or more in the hands of children. I was pretty shocked. I did have a paper wad cannon that had a spring that was printed all in one inside the barrel. The first few had issues with the compression spring breaking when over compressed by the kids. But a bit of a redesign of the spring by making it beefier, it not only lasted nearly the whole school year but the kids got more range. Much to the other teachers and parents disappointment.

    I’ve Printed LOTS of PLA living hinges and even springs. They do work just fine for the limited to moderate cycles they last. I’ve printed 100’s of toy catapults and other small toys in PLA and then handed them out to 8 and 9 year old children. They held up amazingly well under that abuse.




  • Concrete lathes are far from a new idea. During WW1, the US needed more lathes than we had. It could take years for a cast iron casting to age enough sitting outside before you could do the final machining to actually build a lathe.

    So concrete was tried as a substitute for cast iron. It has some good properties, it cures quickly, is rigid enough, and dampens vibrations pretty well. The downsides are you require a physically larger machine that takes up more floor space, and they are difficult to move making resale difficult, and they don’t last as long in that usage, so they aren’t cheaper in the long run.

    Concrete lathes had their day and quickly died out to be forgotten.






  • Short answer is No. It suffers from many of the same issues of echo chamber, bias, and bullying. Just on a somewhat smaller scale due to fewer users. And never forget - Winter is coming. There will be a time in the future the bots will notice lemmee and come for it also.

    But I suspect this is all a human thing. We are a contentious bunch at best and down right hateful at worst. We build communities only to poison and kill them in the end.


  • There has been an effort improve the usability of the GUI. And a pointed effort to create a unified and default assembly workbench that actually works, (it seems off to a good start). Some improvements to the CAM workbench and several others. But much of what other things have been done are relatively minor like improving the solvers ability to create fillets and chamfers without failure.

    But honestly, Ondsel has been very open that the main goal with the 1.0 release is the TPN resolution and far less about new features.








  • FreeCAD’s UI is good enough to work, but not to everyone’s taste. Personally, I detest the clown car UI of Fusion and it’s lack of customization for my work flow - custom pie menus rock. Something that FreeCAD allows the user to do. Not to mention the half-assed mix of local install/cloud that is Fusion360. It locks your projects in the cloud subject to AutoDesk’s whims, but eats your local storage. At least OnShape and TinkerCAD is all cloud and honest about it. But it’s all pay to play if you want access to the good stuff.

    They are improving the FreeCAD UI slowly. The Ondsel version, (based on the 0.22 Dev release), gets high marks from a lot of users about the UI design. Not my personal cup 'o tea, but I do see the allure for many users. Besides, if you don’t like how it works, you can easily customize things to your personal tastes.
