Looking for gear drive parts for 3Dservisas.

I’m looking for a wheel pulley and pinion for a 3DServisas gear drive. I’m currently using a 5:1 gear ratio.

At some point, the gears became misaligned due to an impact, and I continued riding without realizing it. Unfortunately, this caused damage to both the wheel pulley and the pinion.

Since 3DServisas has gone out of business, I can no longer get replacement parts from them.

If anyone has these parts for sale, or knows of any compatible replacement parts or alternatives, I would really appreciate it if you could let me know.

Thank you!
