This is a HAM logo model.
Update: Made a model with coil thickness 1.2 mm instead of 0.8 mm. Both models are included.

I printed it with PLA plastic, extruder temp - 200 deg C, bed temp - 65 deg C, 0.1 mm for layer. I used several supports, but coil loops without support also printed well. Raft is on your decision, maybe it is not needed due to big surface.
