Play a bit with infill, it is designed to withstand 2kg with no infill and 4 wall lines,
I also recomend using support everyhwere and you can scale it first to test your print settings, overhangs etc. This is my first model, if you need anithyng comment it!
RECOMENDED(what i've used):
print at 45-50% scale first and test it out
layer height: 0,15-0,2
wall line count: 3
infill:0-5%
speed: inner walls:65 outer walls:45
scale of the model :47%
cooling 100%
filament temps: high
