I've been wanting to get a 3D printer for a while, but I'm only going to get one once I can make my own 3D models in Blender.
I'm planning to learn using this course which a few people I've spoken to say is a great way to learn:
I think I might start with something cheaper like that little Bambu Labs A1 Mini. I need to get this done before I start my Ghost S1 build later this year as I want to print a fan mount and some cable management clips for it.
If you're wanting to learn 3D modeling...the two go hand in hand. Although, waiting isn't a bad idea. FDM and resin printers are both advancing massively every year--the result being high-end fancy features became "cheap" and normal.
