Few years ago, I had serious doubts about if 3D printed gears would work for most of my needs. Today, I have solved and used 3D printed gears for various purposes but mostly for my RC designs with success!
Old Price: 5
These would be the pinions you need if you started with some of my 1/10 RC projects, as they use Mod 1 pitch gears, the same as the suggested to buy central differentials. They all have a presure angle 20º.
I use to supply the 14T Mod 1 motor pinion with chassis, but probably you want more final speed or more torque... then is time to change that pinion for a bigger or smaller one ;)
You will find pinions from 10T (teeth) to 23T, for both M3 and M4 grub screws, those are 28 models!
The pinions have the number of teeth over the hub part, I hope that helps identifying them when you have a bunch around there.
I have also made some chanfers so you avoid partially the problem of first layer elephant foot, anyway try to do your best for the first layer.
Do your best to print them, ensure your teeth are filled as much as possible with perimeters selecting the best perimeter thickness for the case. I think 3 perimeters for walls work well for most cases.
Print them solid and try to keep the start/end of the loops away from the tip of the theeth, near the center. 0.2mm layer heights will work great, but smaller ones could give you better results.
Search for great inter-layer adhesion so you can really screw the grub strongly and have a durable connection.
Enjoy your functional prints!
