@keldandorin You'll need to install the development version of MySensors, or downgrade the esp board definitions. See https://forum.mysensors.org/post/92176 for more details.
Separately from this, you can find a local 3d-printing service on 3dhubs.com - I found one local to me this way, who did my first print, which got me onto the 3d trail (I subsequently bought a Prusa i3 MkII kit).
