Not my best design, but it works.
Attention: it's pretty easy to print honestly, i even compesated the line width so it's a bit over-dimensioned. But, please, if you see something strange happening in your slicer: just play a bit with the extruder value of your machine (set it a bit lower then the actual one, i.e. 0.35 if you got a 0.4 extruder and then tune a bit the flow). Just remember to reset it right after.
edit: v2 is a lot lighter.
