2mm thick - various diameters
have a version 2 of the template that does circles from 10-22 ..
As can be seen, I didnt have the bed up to temp and so things didnt layer down nicely, also i didnt clean the circles with drillbit or round file or even piece of sandpaper, all would have made for smoother lines on the output. V2 is thicker, bigger and has larger circles.

u vant to make vun ? u must learn ze design tool .. yes .. zis iz vut u need 2 do....
