Getting Started with Creality 3 Pro

[curious aardvark]

well good luck with the printer - hopefully you'll get one that works :-)
(with any ender it's something of a lottery).

It should come with an sd card.
Though they tend to be very low quality (not just creality, most printer manufacturers send out crappy sd cards).
4-8gb tend to work best, and you don't need anything larger.

Best slicer would probably be the prusa slicer: https://www.prusa3d.com/prusaslicer/

best source for models is thingiverse - so create an account there: https://www.thingiverse.com/

Tinkercad is probably the easiest design program to learn: https://www.tinkercad.com/

Depending on the print surface that comes with it, is probably worth your while getting some cheap - blue - painters tape and some pound store gluesticks in stock as well.
Or you could start where you mean to be and buy a cheap self adhesive sheet of PEI from ebay.

Looks like it comes with a removeable print surface, no idea how good it is - so definitely get some gluesticks - just in case :-)

You can always stick a thin sheet of pei over the existing magnetic 'plate' if necessary.

And of course get some pla !
I find that silver/grey, red, white and black tend to print best and with least hassle.
I've used everything from top of tha range polymaker, to ebay's cheapest - these days there doesn't seem to be that much difference between them.
Also get some cheap flexible pla - it's a lot easier to print with that tpu - particularly on a printer with a bowden extruder. It will print, just very slowly and fairly hot :-)

Some cheap spray paint is also a good idea: silver (car chrome paint from the pound store) and a pound store gold, work well :-)

Some foam sanding blocks and some mini files are also a good idea.

That lot should keep you going for a while till you've worked out what needs doing to the machine.
Also watch a LOT of 'I have en ender 3 pro, how do I make it work ?' youtube videos :-)

And good luck !
