I’m working on my “Overkill Enclosure” (T-channel Aluminum and Plexiglas) and I needed to create a Duct to allow the electronics to breath fresh air. I designed this in Fusion 360 - http://a360.co/2nRzWv6. It’s basically a square tube that will seal off the Fan End of the electronics and penetrate through the plexiglas panel nearest to it - a duct. The wall thickness is 2mm throughout. I had good bed adhesion, but the corners all split once cooled. It’s printed in ABS at 240/110 on my Taz 5. This was only a test print (I had some pink loaded) and dimensionally it’s very good. I need some advice on how to minimize the corner splits.
(Corners are square and vertical - camera warped them)
Will a higher extrusion temp help?
Should I add more material to the corner?
Any ideas would be welcome.
