This really depends on what you’re watching it on. 480p can look fine on a phone but like garbage on a 65" OLED. I find that 720p is good for most shows that aren’t visually stunning (like Foundation) while most movies look fine in 1080p on the aforementioned OLED.
This can work fine if you’re just a single user/household since you can ensure that you’re only acquiring audio/video codecs that will play without transcoding but gets more challenging if you’re also sharing remotely with others since you don’t necessarily know what devices they’re using to watch which may require transcoding.
Watch out for overhangs on models. Every feature needs a surface to print on.
Also, probably not such a thing anymore, but give some time to get to know your printer before doing mods to it. It’s near impossible to troubleshoot issues when you dont know whether the issue is caused by a defect with a new printer or something caused by a modification.
Keep your filament stored in something whether it be ziploc bags or those fancy filament storage containers. Also get some desiccant and hygrometers so you can actually dry and measure. I have found the desiccant bags to be pretty worthless while the little colored or white balls/pellets work well and can be recharged.
