Is it possible? Yes. And you've mentioned stability could be an issue. I'll add that if you count your time and wasted plastics to test the thickness, infill, etc. I think it'll cost more than just buying the extrusion.

That said, if you already have core xy printer, you can start testing by replacing the frame with a printed parts. Starts with the vertical ones.

Streisand Effect will kick in soon. I don’t even know any deep fake porn sites.

Can others hear whatever’s playing? Like if I’m wearing it on the bus or in library, can others hear my music?

I’ve never used one, but I’ve read reviews on the cheaper ones, they said it’s just speakers in front of your ears.

1. If micro stepping varies that much then FDM printers (and CNC machines) wouldn’t have worked so well. Also, you can tune the micro steps, if you need 410 steps to move exactly 10mm instead of the default 400, just change it. (I just pull a random number btw, it’s been at least 5 years since I touched my Marlin firmware)
2. If you’re familiar with coffee grinders, they’re basically using thread to adjust distance between 2 burrs. Even there (mid to upper-mid range ones) can’t guarantee the same grind size on the same setting for different unit of the same model, eg. setting 11 on grinder A will have slightly different result compared to another unit of grinder A on setting 11. Can it be done? Yes, one example is Commandante, that is a $300 hand grinder.

Tight tolerances will exponentially skyrocket production cost, period.

It’s extremely expensive to produce things with tight tolerances. Cheap 3D printers have gotten away with it by making things “good enough”. Which why you got this the other way around;

In short, instead of an arbitrary number like 0.3mm that has no meaning to the user, they tell the user to turn this knob 1/4 of a turn. An instruction the user can follow.

0.3mm is easy to measure with the right tool like digital indicator. On the other hand, quarter turn on a knob might adjust 0.3mm on one bolt, but 0.5mm on another.

Also as mentioned, ABL, cheap and can be DIYed. Cheap / printed parts can warped over time, bolts can shaken loose, etc. ABL just put these out of the equation.

Turntable uses needle to feel the “bumps” and turn it into sound, if the needle can feel dusts (which is why people always wipe them before playing), it can definitely feel the layer lines.

Dusts are like what single digit microns? while the best resolution for resin printer is at 10 microns.

I just use the cheapest fruit dehydrator and snips away some of the trays.

I've been using https://utteranc.es/, same concept but using Github issues as comment. This is interesting, especially if there's a way to handle each user's instances.

Moved to Firefox when adblock stopped working on Safari. The biggest hurdle was moving away from Keychain for password manager. Everything else was a non issue since now iOS allow others as default browser.

Email and calendar I’m on Spark, not ideal, but it works for my workflow.

Notes: Simplenote, better syncing across platforms and free.

Overcast, Spotify for music, quite generic.

What is VSO?

I just plug 500gb usb stick on my Asus router (Merlin). Install transmission, and turns on vpn and smb share. Playback is using iina on Mac, mpv on Android, and Outplayer on iOS.
