[Self-made Test Model] 3D Trainchy

3D Trainchy: A More Challenging Test Model Than Benchy

This model began creation on May 23rd and after two days of refinement, it was finally released.

This model is a toy-like test model, similar to "3D Benchy," but I have enhanced its testing aspects and playability.

Here are some testing aspects:

1, First Layer Adhesion Test

The model's first layer has six minute parts and bottom text, which severely tests the first layer adhesion. The image shows two of them.

2, Overhang Capacity Test

The model's wheel holes and hubs have tests for overhang and heat dissipation, referring to the hole heat dissipation test at the rear of the Benchy.

3, Hinge-type Model Precision Test

The model has three carriages connected by hinges, testing the printer's precision control of hinge-type models.

4, Rear Smaller Overhang/Text Detail Processing Test

The model has a circular window at the rear, with "#3D Trainchy" printed below it.

5, Small and Medium Bridging Test of Bottom Text

There is a string of text with 0.4mm spacing under the three carriages at the bottom of the model. When printing to the third layer, it needs to bridge directly over the text, testing the printer's bridging ability.

6, Classic Cylinder Test

The model has a cylindrical chimney at the front, referencing the chimney of the Benchy.

This model references several design aspects from 3D Benchy, including:

1, Chimney

The chimney section references the "cylinder test" of the 3D Benchy

2, Bottom Text (Bridging Test)

The bottom text references the text bridging test of 3D Benchy.

3, Rear Text, Hole Heat Dissipation

The rear text references the text detail test of 3D Benchy.

This model enhances the test items and playability of 3D Benchy. It can be used to test the performance of the printer, and also as a toy. Trainchy is a more challenging model with more test items. As a new MakerWorld user, I hope this model can provide everyone with a better test model and bring more joy!
