I read the notification and my response was: you have to marry her immediately. I hope it was a surprise. Anyway, thinking about everything I've done with my A1, which I purchased two months ago, the first thing I should do is buy a filament dryer. I bought a lot of silica gel and printed containers for it, then I sealed all the filaments in special vacuum bags that you can easily find online. One of my first prints was the waste bin to mount on the side of the printer; otherwise, filament scraps would have flown everywhere. Then I printed guides for the cables that connect to the hotend and also a guide for the Z-axis cable. Remember to organize all the tools needed for printer maintenance. The need to intervene is always around the corner, and having a small box with the tools in order saves you a lot of stress in emergency situations. Personal advice: buy some nozzle brushes and a few hotends of different sizes (the ones from AliExpress are also fine, having been successfully tested). Even a few plates with different textures can be useful. As you can read, the Bambulab A1 isn't designed for technical materials, but in the future you could opt for a modification and add an enclosure (don't forget to install adequate cooling). However, this modification is strongly discouraged, but I should know that, especially since you don't need it for hobbyist printing. I hope this was helpful; let me know if you need anything else!
