Trying to print 40 teeth gear, (10.48,10.48 and 1.5mm-XYZ). Its seems that gear teeths are not meshing. Plz help

Hi, I am using CURA to print a gear model. XYZ (10.48 10.48, 1.5mm), Almost gear is coming like circle. I have tried to print 2 models and trying to make meshing. Pls can you send .stl file or settings.

It could be useful for me. Neglecting the hole of gear.

The diameter of the extruded filament is likely too large. The only way to get this detail would be to use a smaller nozzle.

With a standard nozzle the extruded "sausage" is 0.4mm wide. But then it gets squeezed onto the model and spreads a bit. So, it will be hard to print lines and corners smaller than 0.6mm to 0.8mm. Maybe it could be done with a 0.25mm nozzle? But I still don't think the gear will mesh properly and run smoothly.

Anyway, for best accuracy print slow and cool (e.g. 185°C for PLA).

Also, keep in mind that if you print the gear in PLA, and it has some friction or is mounted close to a motor, it will deform from 50°C on, which can be reached very soon in an enclosed housing. So you might need a high temp material (and one that can be printed with a 0.25mm nozzle, but I don't have any experience with these).

For functional items, I think you are better off buying these gears.
