Quoted from Pinbub:
How do I go about paying someone to 3D print Pinball parts for me? I know I can probably pay someone locally to do it who isn't into Pinball and they'd do a one off and probably never make another unless it was for me. I figure if I can pay a pinsider to do one they can save the file and print and sell more to others. Can I pay someone here to print me a part? I'm looking for a drop target for an allied leisure cocktail pin. I know there are other people looking for these and if someone would print the plastic pop bumper rings apparently people need those as well. Please message me if you offer printing services or can recommend a Pinball enthusiaist who does. I can supply a sample of the part I need.
You are asking two things:
1. Someone needs to design a part as a 3D model
2. Someone needs to print a part from a 3D model
The first question is tougher as designing ANY part is time consuming. You'll need to find someone with time on their hands, or someone with the same need for the same part. They need to create the 3D model, with exact dimensions, which takes a fair bit of time and usually requires access to the original part to get it right. Good that you have an old one to get the designer started. They essentially are copying the physical part into a 3D model with some kind of CAD 3D drawing tool. My guess is several hours to copy a simple part, or longer for one with lots of detail.
For the second question, try https://craftcloud3d.com/
Once you have the 3D model, it's easy to print it. Today, many 3D printing shops are low cost, and from time to time have free shipping. It's basically a clearing house for 3D printing shops. I have used a few times with great results. You can choose the color, material and which location you want it printed from. (hint: consider choosing one close to you)
