Hi GR5
Yes your right - i looked and it showed the support as you said. But i do agree - best put some supports in cad - especially for those canitlever bits where there is nothing underneath. I should have added something thin in CAD that i could easily remove after it's printed.
My CAD skills are poor as i normally have a cad guy at work to drawing work for me. I am using a 30 day trial version of ACAD that i am playing around with at home. Took me about 10 hours to do that candle thing - thats how poor my cad skills are.
Many thanks again - am learning slowly.
