Results of tuning, before and after… I might try to tweak it a bit more, got some dotted lines on the first layer, maybe a little bit too much under extruded. I wonder how hard it would be to update the model to use 22awg wire? I ordered a magnifying solder helper with a light to assist. @22awg the channels could be 2-3 “lines” wide at .2mm. If I had skills beyond tinkercad I wouldn’t ask how difficult design changes are. :) LOL.
