Thanks. I hope it works out!

You seem like you know what you’re doing, but since you mentioned it:

If you’re worried about leaks, you can use Nylog White on the threads. It’s food rated and works for your liquid and co2 gas connections. In theory, it’s also not supposed to harden and make your fittings impossible to unscrew.

Looks like 3/8" NPT Schrader valve connection to me, but I’m not an expert on the matter.

Very satisfying to click around. Makes me wish the US would build a decent passenger rail network.

I’ve seen some videos where paper shredders have been modified for this purpose. I don’t know how consistent the filament diameter was, though.

I would think the best way would be to first melt the plastic into a wider intermediary filament and then pull that through the desired final extruder to get a more consistent result.

I’ve been working on an openly documented recycling solution that would make use of litter from my area (mostly less commonly recycled plastics like polystyrene and LDPE), but I’m still in the identification/sorting phase. Finding an infrared spectrometer or sensor for the 1000-2300nm wavelengths to properly identify plastics has been difficult, but I think I’m close.

You don’t need an online community to freecycle! Friends and coworkers often have old laptops and monitors lying around and some are also in need of laptops and monitors. I clean them up, do a proper drive wipe, install the OS of choice for that person, and pass them on to their next owner. Anything to prevent working hardware from going to an e-waste bin.
