griff851 wroteVery cool. Result.
My mate is using a 3D printer to make inlet manifolds and velocity stacks for 250 yamaha’s. He’s also built a hugger for cbr250rr. I’ve been privy to all the drama. Flimsy rigs, dead mother boards, humidity screwing around with nylon stuff he was using etc etc. Open the box, plug it in and away we go it is not. Nice one.
So what’s the theory on why the inside went weird arse? You can see clear bits on the thread in between lumpy bits, and good on the other side. Sort of looks like heat damage from warming little bubbles. But why only on one particular surface., which would mean
Coordinate’s issue. Have fun with that. 😁 Out of my league. 😁
The view you get is from the underside of the part as it prints. As the filament retraction is turned off for soft filament (to stop clogging), these are just small stringing remnants left behine. From above it is clean, but these are just "hanging on".
I just did the wire brush treatment with a dremel and it looks much better and goes on the tube faultlessly. Attached Before and After photos.
