Dear Forum, I have a question: How can a tube be built with a clean 90 ° without sticking to pieces or secmete to gluin? Please see attached pictures.
Also there is a picture of my current build and it is clear thi looks not good.
I like to make in a diameter of 6-8mm some pipe work. Actually they should be able to transfer some air.
Task is to build the 90° and 45° bendings as ' natiral' as can.
