Fitment Notes for Printed Parts

Printed parts should solve problems, not create new ones during install.

Fit should be deliberate

A part that requires extreme force is usually telling you something:

• Tolerance stack-up is off
• The mating part has variation
• Print settings changed the final dimensions
• A burr or edge is interfering with the install

Recommended approach

Before modifying a part aggressively:

1. Dry-fit without hardware.
2. Compare contact points and look for witness marks.
3. Confirm the install direction and intended orientation.
4. Remove small interference points in a controlled way.

Avoid common mistakes

Do not force a part just because it is “close.” That often hides the real issue and can crack a printed component or stress the surrounding assembly.
