rclone to dropbox and opendrive for things I care about like photo backups and RAW backups, and an encrypted rclone volume to both for things that need to be backed up, but also kept secure, such as scans of my tax returns, mortgage paperwork, etc. I maintain this script for the actual rclone automation via cron

A big important question is do you want your hobby to be 3d printing or 3d printers? If it’s 3d printing, save up and pay the premium for one of the more appliance-like ones that just works out of the box like the Bambu X1 Carbon. If it’s 3d printers, the skies the limit because you’ll probably end up replacing almost every part over time to upgrade/tweak everything
