My sister Jane once asked for a horse because "everyone in her class has a horse".
Sometimes it feels that way with 3D printers. Several people have recommended the Creality Ender-3 printer as a good starter model. I ordered the Ender-3 v2 and paid AU$360. (Excellent value).
What arrived was a well packed kit. The base is already put together but you need to do the rest.
They do supply everything including tools such as hex keys, screwdriver, spanners and even side-cutters (which are used to cut filament). I was a bit daunted by the process but took my time and it came together.
STL files can be loaded from a micro-SD card. They supply a card but my printer wouldn't read it for some reason. I formatted another card FAT32 and that worked fine. I was unsure that I'd got the base level enough but my first print, the Chinese cat you see below came out impressively well:
As you can see from my early prints here, my first use for a 3D printer is to make tuning knobs for radios. (Oh, and toys for the grandson).
There are many pre-made models ready to slice and print at Thingaverse, Thangs, Printables and others but I want to be able to design my own.
I scanned my face with the iOS app "3d Scanner App", exported to STL, imported in to Blender to tidy up and printed it:
