We are printing parts for miniature tanks.
And we had a lot of troubles with the support destroying the outer line of the model.
So our idea was to draw a wall of 0.1mm thick on the sides of the model.
Results with clean up
So this is very good solution for this problem but it’s very difficult to draw on a curved line.
For example for the middle hole. It’s not perfect round…
Maybe this option can be added in Preform? A line support on the sides.
Or are there easy solutions to draw these lines yourself?
