3D Print Bike Handlebar Accessory

I need a bike tagalong adaptor 3D printed (weehoo tag along - seat post adapter - sits under the bracket that attaches the kids bike to the adults seat post). I have a model file ready for use. The part should be made of plastic (strong as it will be under quite a bit of stress).

Ideal Skills:
- 3D printing expertise
- Familiarity with bike parts
- Proficiency in handling plastic material

Expectations:
- Accurate reproduction of provided model file
- Delivery of high-quality 3D printed part
