I did this print just to joke because I thought the printer would never finish.
But ... it finished !
The filament is a real PETG (+2% extruder flow ratio) printed at 250° with bed at 70°, fan forever at 100%.
Attach surface is 2.5 x 45 mm.
Print finished:
After a fast clean:
Petg has mush adesion to the plate and raft ... i would try with ABS ...
