What printer around 600€

[curious aardvark]

qidi one: https://www.amazon.co.uk/QIDI-TECHNO...words=qidi+one
Looks decent. Basically a finder, but with heated bed and cheaper :-)

wanhao duplicator i3 plus: https://www.amazon.co.uk/Wanhao-3d-D...icator+i3+plus

Good kit.
Hell get an i3 plus and a he3d delta k200 kit and it'll still be cheaper than the qidi dual extruder :-)
Actually for the 2 it would be almost exactly what your refund was. It's a sign !

3d printers are like chocolate, one bar is good - but two is always better :-)
