Designed carfully bymyself this motor contains every single functinal piece in an actual DC motor and can be simulated in solidworks. Designed in SI units this motor can be easily printed and used for educational or commercial purpose. There is also a video uploaded among side of the zip file for the motor which demonstrates the functinality of the motor by displaying me simulating the motor in solidworks and spinning the gears of the motor's gearbox. would have sold it way cheaper but the minimum sale limit is 3 dollars.
