I will post an update with paint but wanted to put a warning : the underside is not flat. I had to lower it by 0.3mm to have a good slice.
0.08z - 0.3nozzle
thanks for pointing that out. I had sliced the bottom in editing and hadn't noticed a small bit left, which caused the base to sit off the build plate.
I have fixed this.
thanks for letting me know. completely missed that.
Happy to help !
It's not the first time I tried to print it. But the first time I do checking layer by layer why it failed every time ...
Future printer enthusiast will have success printing now !
