Infill: 0%, 1 perimeter

Filament: Spectrum PET-G Lion Orange

Notes:

Printed from PET-G, nozzle size 0.8mm, one perimeter and 0% infill, this produces fast print and is overall OK.

Insulation mat comes from here: 

Buy the 220x220mm version (for Anycubic I3 Mega), cut corners and insert it under hotbed (no need to dismantle the bed). Then fix it with this printed spring, 4pcs needed.
