3D N scale models can be a great way to add realistic detail to your model railroad layout. They are typically designed using computer-aided design (CAD) software and printed using 3D printers, resulting in highly-detailed and accurate models.

When considering purchasing 3D N scale models from any company, it's important to consider a few factors. These can include:

1. Quality: Look for high-quality models that are detailed and accurate. Check for reviews or examples of the company's previous work to ensure that their models meet your standards.

2. Compatibility: Ensure that the models are compatible with N scale train layouts, and that they will fit with your existing scenery and structures.

3. Cost: Consider the cost of the models, including shipping and any additional fees. Compare prices with other similar models from different sellers to ensure that you are getting a fair price.

4. Customer service: Look for a seller with a good reputation for customer service, who is willing to answer any questions you may have about the product or shipping.

Overall, when looking to purchase 3D N scale models, it's important to do your research and choose a seller that meets your specific needs and preferences.

Small Town 3D Models excels in all of these categories. 

Quality: The models are of the higest quality possible in such a small scale.  Nothing is shipped unless it is inspected, cleaned up and inspected again.  Nothing is shipped that wouldn't be used in one of our own train displays.

Compatibility:  All models are design to specific N Scale guidelines and scale. After the first protoype is created, they are tested with N Scale people to see how the scenes fit together with actual N Scale people and cars.

Cost: All of our models are very inexpensive.  The process that goes into these models takes many hours (2 to10 hours of print time in most cases).  After printing they are inspected, any flash is meticulously removed and then inpsected again.  Then orders have to be processed, packed and shipped.  Those hours add up.  Since these N Scale models are not mass produced, it takes a lot of hours to produce just one so you are getting a ton of value for your money.  Most models are less than $10 and mmost others are less than $15.  That's not much for all that goes into these highly detailed models.  It's really a labor of love.

Customer Service: All customer inquires are answered quickly and we do what it takes to keep our customers happy.  We treat customers how we would like to be treated.  That's the only way to do business.

So for your N Scale accessory needs, keep Small Town 3D models in mind when you need some specialized 3D Printed N Scale Models.
