Working Bevel Gear - Example

This is a example of a bevel gear, and 3d printers can print small ones that work.

I would recommend printing at a low resolution and the Main parts Separately.

Print the Gears Separately, 1 at a time/
You can print the shafts, or you can use toothpicks as they are stronger, and easier to work with.
Print the shafts upright with a brim, as it will stick to the bed easier
The TPU is for a type of spacer, using it for its ability to fit with no spacing between parts - usual is 0.2 mm
You can also use tape if you don't have TPU, but use small strips

For instructions, view the cross section of the design I have attached
There is a larger spacer named Spacer - 2, for the gears to mesh properly

There is a longer shaft, which isn't necessary, you can use the smaller one for both gears, if you would like you can.

Attaching the secondary gear while the first one is in place is a bit tricky, you should align the spacer and the gear so that the shaft can fit through, printing the shaft horizontal makes it hard to fit in, as I have said print it vertically
