I’ve personally been quite pleased with the combination of Frigate and some Amcrest POE cameras. Just make sure the cameras you are getting support RTSP though and you should be able to use them with Frigate.
Also make sure you block the cameras from reaching the public internet using your firewall, and only make them reachable from your Frigate host. Personally I use a VLAN with no internet access and enforce tagging at the switch level (i.e. don’t trust the cameras to maintain their own VLAN) settings.
Looks a lot like a carburetor float needle to me. It allows the flow of gasoline into the float bowl, which sets the amount of fuel fed into the engine.
It’s common for float needles (and carb parts in general) to be made of brass, and the wire clip being made out of steel is also consistent with a float needle. The plastic tip is probably used for a better seal when the float is up, closing the needle port.
I wouldn’t bother with vacuum bags If I were you. I think it’s fine if you’re using a drying box after the filament has been sitting out a while. Doesn’t hurt to try and find out at least…
Personally, I just use a big plastic storage bin with a bunch of silica desiccant in it. I just busted out some polycarbonate (notoriously hydrophyllic) recently that had been sitting in there for 4+ months and printed straight away; no stringing or anything.
I use the washable gluesticks for my polycarbonate prints. I just put PC prints under warm water for a few minutes and they pop right off. Gluesticks generally reduce bed adhesion though IME, so it’s a fine line to walk; I never use gluesticks with PETG for example because then the parts don’t stick to the bed enough.
