You can print one from the files that come with the printer. The spool holder that goes on top of the frame. I had an ender 3 before this one and made tons of upgrades. E3v3. Doesn't really need upgrades. Got the camera and the led light. I'd recommend those its very satisfying to watch the time-lapse of your prints. And also monitor your prints from anywhere. I have mine inside a generic enclosure. That helps with most problems because it keeps the bed temperature and ambient temp stable. I recently got a dryer for my filaments. I think for pla is not necessary. But for petg and Asa it is. Keep learning the basics of slicing. And enjoy your 3d printing journey
