Print with PLA+, 50% Infill since this is a mechanical part.
Did this for my father-in-law, which is a technician in vending machines.
The brand don't sell the gear itself, they make you buy a new model of motoreductor, this was made to counter this politics.
The print in photo is the first test, a big larger since I was experimenting, the final print is already back into the vending machine.
The author marked this model as their own original creation.
