You can use most of the connectors you would use for bigger wires. Wago lever nuts are rated for conductors as small as 0.14 mm².

If you want something to fit a din rail, standard terminal blocks (something like this) should also work.

ISO 8601 was published on 06/05/88 and most recently amended on 12/01/04.

From the IRF1404Z data sheet:

Calculated continuous current based on maximum allowable junction temperature. Bond wire current limit is 120A. Note that current limitations arising from heating of the device leads may occur with some lead mounting arrangements.

You need to design the PCB so that the heat from the legs can be properly dissipated, or they won't live up to the rated current.

Also, traces on a PCB are much thinner than those legs. A trace with the same cross-sectional area would be impractically wide.

Unfortunately, SawStart is one-use-only. Once started, the blade cannot be stopped, and must be replaced with a fresh blade while the running one is carefully disposed of.

It doesn't ask you to subtract the numbers, but to calculate the distance (i.e. the absolute value of the subtraction). So depending on which numbers are paired up, the sign of the pair can be different.

I think this might just be a particularly uncooperative tire, but it should work if you wrestle it on there. Maybe post a picture of the whole wheel, there might be something here I'm missing.

Unpopular opinion: The license makes sense and should have been enforced from the start.

The Benchy is a benchmarking tool, not just visually but there are also various features you can measure and check against the dimensions on the website. But that doesn't work if the model you're printing has been modified.

If it looks like a beachy, it should have been printed from the original model, so it's always comparable. Preventing derivatives means you can be sure of that, even if it came on the included SD card with your printer. Otherwise, manufacturers could include a modified model that makes their printers look better than they are.

Every single freewheel does this, and it's not an issue.

The freewheel bearings don't line up exactly with the wheel bearings. This is always the case to some degree, because the interface between freewheel and hub is a non-precision thread.

It might look weird when freewheeling, but once you put use the pedals, freewheel and hub are rotating together, negating this wobble.

If you can wait a couple weeks, AliExpress is going to be the cheapest.

eBay may be a bit more expensive, but it's often my go-to because you can find everything and usually there are options with short shipping times.

For not too obscure parts, I would look at Reichelt, their prices are surprisingly low (especially if you bundle your orders to save on shipping costs).

Can you get a big flathead screwdriver in there to carefully knock it out? It should allow you to get a better angle than the dedicated tool.

Go slowly and alternate the places you're putting the end of the screw driver. You want to push the cup out evenly, or it will jam and possibly deform the head tube.

HiPER Calc Pro. A great scientific calculator I use constantly. (There is also a unpaid, ad-supported version, and the ads weren't too intrusive the last time I tried it)
