Adding tolerances to our designs
Now that we’ve learned about general tolerances for common printing techniques and material choices, we can compensate for these tolerances in our 3D models. This is an important step not only to create accurate models but also when creating multi-part models that must fit together. Let’s look at the considerations for such instances.
Types of fit
When creating successful multi-part models, the first step is to consider the type of fit we want between our parts, as shown in Figure 12.5:
Figure 12.5: Comparing the types of fits between parts
The models shown in Figure 12.5 compare the three general types of fits when creating a multi-part design that has two or more parts fit together, such as the hole and peg shown in these images. A press fit is the tightest fit with the tightest tolerances. This type of fit has two parts assembled in such a way that they are not intended to come apart, and if they...
