Please appreciate this insanely adorable coaster set I 3D printed. Ft weightplates, barbell, and even a squat rack.

Rapidly approaching the "can't be stuck if it's a liquid" stage of trying to get this valve cap off.

im still so annoyed about the (very cool!) planetary gear reduced 3d printer extruder design that had nonmeshing gears on purpose to try and balance out the tolerance issues with trying to 3d print perfectly meshing gears & i commented asking about it and then the description was updated to be like "SOME people have asked for a 72t (or whatever) version, even though i designed it like that for a reason, so if youre really anal about gear ratios you can try it out. youll probably have to run it in for a really long time to get it to go smoothly if you dont have good tolerances, and my first design was literally fine, but here you go. UNRELATED: in the next version were moving to sls printed part kits because theyre more reliable and have better tolerances so thats very exciting :D" like so then i was RIGHT!!!!! is what youre saying!!!!!! bastard!!!!!!!!!! and he already warned that a run in period was mandatory on fdm printed sets anyway even with his design!!!!!!!!!

Is spider silk being as strong as steel another lie from childhood? Bc you're able to break it pretty easily on accident. Genuinely asking.

spider silk IS actually significantly stronger pound-for-pound than the same amount of steel, but only in one direction! and coincidentally, it's the same exact direction that got a bunch of people killed in a submersible last month.

see, when people talk about the "strength" of spider silk versus steel, they're specifically talking about tensile strength:

which is specifically the measure of the strength of a material when two forces are pulling at it from the ends, like when a steel cable is holding up a bridge support, or crane cargo:

or like when a strand of silk is supporting the entire spider.

that's tensile strength, baby!

but there's another type of strength that's very important to take into consideration when you're actually building things like bridges and submersibles, and spider silk and similar materials like carbon fiber are absolutely garbage at it! and that's compressive strength.

this is basically the inverse of tensile strength, where instead of being yanked at from both ends, the forces are crushing inwards at the material from both directions instead.

you can expect to see these kinds of forces involved in road surfaces, vehicle engines, and again, submersibles.

now steel and its more competent cousin titanium are fucking GREAT at compressive strength! the harder the outside forces are compressing them, the stronger the metals get.

NOT TODAY, FUCKERS

but strand-based materials like spider silk and, again, carbon fiber, are fucking garbage at this. they can take a certain amount of pressure, but each round with compressive forces snaps some of the strands that makes up the material! and those don't grow back, so basically you're just gradually reducing your poor overstressed carbon-fiber hull into a completely useless shell of shattered thread fragments over time as the strands of fiber that actually give it strength die off one by one.

and eventually, something's gotta give! and then people die about it.

this is why, even though spider silk IS stronger than steel in one specific way, we're never going to stop using steel in industrial applications and switch over to spider silk or carbon fiber full time. these materials all have their areas of use, and steel just covers a wider base of applications.

and don't even get me started on shear strength. we'll be here all damn day.

gymnasts: i just completed an insane bar routine with a bunch of pirouettes and handstands. oh my hands are bleeding profusely because i ripped all my calluses? didnt even notice lol

me: omg my lil baby callus has started ripping at the corner, to reveal a smaller, identical callus underneath? sorry but i simply cannot continue this 115 deadlift

Fastening connection function:

In mechanical equipment: used to connect two or more mechanical parts to ensure the stable operation of the equipment. For example, in some small transmission devices, instruments and other equipment, circular knurled nuts can firmly connect different parts together, withstand a certain vibration and tension, and prevent parts from loosening or separation.

In the field of construction: It can be used to connect various components in the building structure, such as in steel structure buildings, round knurled nuts can be connected to steel beams, steel columns and other components to ensure the stability and safety of the building structure.

Easy to manually operate and adjust: The pattern on the surface of the knurled nut can increase the friction, and it is convenient for people to directly twist the nut by hand without the help of other tools, which is very practical in some occasions that need to be adjusted or disassembled frequently. For example, on some equipment that requires frequent adjustment of height or Angle, the use of circular knurled nuts can be easily adjusted manually.

For injection molding and embedding process: In the injection molding process of plastic products or other materials, the round knurled nut is pre-buried in the mold, and then the injection molding is carried out to make the nut and the plastic part tightly. This can form a strong threaded connection structure on the plastic products, which is convenient for subsequent assembly and use. For example, in the shell of electronic equipment, auto parts, toys and other plastic products, this kind of embedded round knurled nut is often used.

As a connector for thin plate connection: in the connection of some metal sheets, such as in the manufacture of chassis, cabinets, metal furniture, etc., round knurled nuts can be used with the pull riveting process. The nut is fixed on the thin plate by the rivet gun to realize the connection between the thin plate, which is both firm and beautiful, and can avoid welding or tapping operations on the thin plate, and reduce the damage to the thin plate.

In furniture manufacturing: used for the assembly and connection of furniture, such as the frame connecting tables and chairs, the panel fixing furniture, etc. The appearance of the knurled nut can be selected according to the design requirements of the furniture, which meets the functional requirements of the connection without affecting the aesthetics of the furniture.
