need these so bad

that it is!

nah the cutouts are too deep to go in at a angle

niceeee this is a good Lego set

It’s a zip tie

The alignment is already thrown off from taking the gun off, relocating the microscope, and putting the gun back on, so it has to be tuned again anyway

Thanks!

thank you !!

TGIF (thank god it’s field emission)

even JEOL makes cutouts around column bolts so shallow as to require Extra Short Screwdriver

damn that’s crazy

I love these things, these are just a few of my collection

Also I do research using ultrafast pump-probe electron microscopy, where multiple laser beams are coupled into the microscope, so the microscopes I’m around tend to have extra holes in them

The first time I showed them it was randomly viral so now I think it’s funny to take pictures of them whenever I see them in labs. Most Thermo microscopes seem to come with them these days.

What he said. Usually the special screws are used on the cover of a port into an electron gun, column, or chamber, which may be used to inspect the source or to bring light in or out of the microscope.

X-ray safety screwdrivers keep finding their way to me

that’s some very nice deflection 🫶
