Ah, that makes sense. Looking at the FAQ page, it appears anyone who pays for the non subscription FSD gets the upgrade free, subscribers have to pay $1,000 for installation.
Same page says there is a camera upgrade available for some s/x/early 3s also restricted to purchasers of FSD.
All the Model 3s with v2 were offered a free upgrade, I suppose there could be some people that never bothered and then sold their car, but if it’s in Tesla’s resale inventory I would expect them to have done the upgrade.
My 2018 Model 3 got the upgrade and I use FSD daily, though it still has the older revision of the display (just slightly less responsive in web browsing and games).
I can give this advice because this is where I’m stuck hah.
I have tried retrofitting paper shredders and blenders and not had much luck getting small, consistent shreds to use in my filastruder (which is also jammed and was always finicky).
If your plan is to recycle old prints, you should try shredding what you have first. That way, you will realize it is ridiculously difficult without spending thousands.
Filament is so cheap these days, it’s really not worth making your own with 100% new material (+ colorant) and shredding old prints down to granule size is too difficult to be viable for low volume.
Someone made a parser for the Google QR codes and now some apps can import them directly. I switched to aegis this weekend and it worked perfectly.
