Below is a 3/4" BSPT to 1/2" NPT adapter that is still warm. It's in Taulman Nylon 230 which means it can be printed at 230C, which is about all the XYZ Pro is capable of.
Sorry for the fuzzy image. The threads are actually quite good.
How’s your results with nylon? I’m printing model battleship detail parts (turrets, etc) in ABS at 255 degrees on my Prusa, and it’s going well, but I might be interested in nylon if it was user friendly/durable/etc.
(If not, I’ll just stick with ABS, it seems to get the job done.)
As for the ping list, count me in, if I’m not already.
Thanks to all the responders about the wagon wheel shape. So, sacrificial material is laid down first, that’s clever. You mention that a “slicing app” will add the support for me. I take this to mean the 3D design software where the print design is created? That actually brings me to my next question. You have to have some pretty solid 3d design skills to make that adapter, to get those threads modeled correctly, etc. What 3d modeling program should I start with if I wanted to make a printable model? Freeware is always nice to learn on.
