Travel lines viable on top surface


Recommended Posts

Posted · Travel lines viable on top surface



I recently start 3D printing. I made just a few prints. I'm creating some objects for my home automation system.


I designed a PIR sensor holder to mount in a electrical wall box, wich is fine. But now the issue/improvement, there are some travel lines viable on the top surface. Its exact the blue lines of the first screenshot I added. 



I tried changing the travel settings like Retraction and avoiding but withouth succes. 


Is there any way to improve this? Optimal would be no traveling at all at the last layer, isnt it possible to print one of the top lines instead?


Any suggestions on the design itself are welcome to, and maybe someone could use it. It is for a normal arduino PIR.
