On another note. Just finishing up a phone mount for my tripod.
Using pet-g on the delta.
Gotta say, it's looking bang on. really clean print.
The PET one got broke somewhow, think someone knocked it over and never mentioned it.

So thought I'd go with petg. guessed (at this point, it's not really 'guessing') the numbers: 245 on the nozzle 65 on the bed and 60mm/s max speed, and 0.3mm layer height with a 0.5mm nozzle.
Not a spider web in sight :-)
