Hi guys,
I tried to print this Y nozzle by placing it flat on my Afinibot Prusa i3 and also making it stand.
Both ways didn’t work.
Is this something to do with my setting on Repetier Host or ?
Appreciate it someone can assist.
Thank you.

What slicer, material, temps and speeds?
Haven’t used Repetier so I’m no help there! It says it used Slic3r to generate the gcode? If so it looks like an old version so maybe an update is worth looking at.
Temp is pretty good. You might try going lower in 5 degree drops and see how the filament does but still pretty good at 200.
I would drop overall print speed to 30-35mm/sec or so. You will want slow to allow the layers to cool a bit especially on a smaller part.
If you have a part cooling fan make sure it is on after the first layer or so.
Is it really a .5 nozzle? How big is this part? It looks like it should be able to print ok. I think speed may be a factor.
Looks like you need a filament cooler, the layers are drooping before the next layer comes in, try slowing down the print speed.
You might increase the extruder temp a little for better layer bonding but not to much. Try 205 and see how it goes. I would measure the filament diameter in several spots and enter that average in the slicer. The horizontal lines may be a mechanical issue or the extrusion is off but one thing at a time.
That split in the middle could be the model and not the print. Not sure without looking into it more.
The current extruder temperature is 205. I didnt increase it further yet.
I think the split is also due to the model, but I’m not sure how to improve it.
Thank you for your replies so far.
You may want to run the model through a fixer like Netfabb to see if it finds any issues.
I see the cracks, how did you create this model? Are you sure the model is 1 solid and not two solids “very close together” I have seen this happen on one of my prints where there was actually a very small gap where parts met. When this part was printing, did you watch the nozzle as it printed the upper portion of the part? did the nozzle print each side separately? if it went in a figure 8 pattern then the gap would not have been there.
Can you post the 3d model file (STEP will work) or the STL file?
The nozzle printed both sides together, then towards the end, focused on one side and ending it before moving the other side.
I am attaching the stl file.
The stl file had some manifold problems which i then got it fix on netfabb.

Actually when i uploaded my initial stl into Repetier, it says object is not manifold and asked me to fix it using Netfabb.
I did and here’s the fixed stl file.

I’ll give it a try this afternoon if I get a chance. Curious to see how it does since it does!
I saw this also when importing this into Inventor.
Thank you for looking at my file.
It means that there is a problem with my drawing, right?
Actually, I’m a newbie in drawing too. I drew the nozzle following a guide on youtube.
So if someone can tell me what is wrong and how to correct the drawing I’d be grateful:)
Thank you.
Here is a quick model made in inventor of your nozzle, the dimensions are not exact, hard to take measurements of a mesh model. Steps are create the lower cylinder, draw a line from the center at an angle, draw a rectangle and use the line as an axis of revolution, repeat. Perform a Shell operation, finish.
