I will have to try this one.

Let me know how it turns out or if the design needs any changes.

try it with "vase setting" !! often I'am curious as to how parts made in this fashion turn out!


On 2nd thought..the overhang requires supports.. but if modified slightly..

I printed this today, the design is good but the silky copper filament I'm using needs work. I've also printed the BT-55 nozzles and they were great too. All printed with no supports and came out fine, except for the aforementioned filament issues. Thanks, Jack!

You printed it with silky copper filament? Wow! Can you post a pic? I bet it looks great!

 

[Honest John]

Sure thing, here you go. Still trying to dial in the settings for this stuff. It looks great but prints terrible.

Printed on an Anet A8, TTTYT3d Silk Copper PLA, 210 C, .2 mm layer height

Wow! That looks great!

So just for a goof I tried vase mode, and as you predicted, the print failed at the shoulder due to a lack of layer adhesion. That said, the parts the did turn out ok looked amazing in the silky copper, but they were ridiculously weak.

The part would have been usable for a static display piece, even with the section that failed because it wouldn't have been noticable once glued in place.
