Manual Projector Square and Round Endcap

1. **Round Endcap:**
  - The endcap should fit securely onto a projector housing with a diameter of 7.7 millimeters.
  - Verify that the inner diameter of the endcap matches this dimension to ensure a snug fit onto the projector.

2. **Square Endcap:**
  - The endcap should accommodate a square projector housing with dimensions of 13 millimeters on each side.
  - Adjust the design of the square endcap to have inner dimensions that align with this square shape.

When 3D printing the endcaps, verify that the inner dimensions match the specified diameters and square dimensions to ensure compatibility and a proper fit with your projector. Testing prototypes is recommended to confirm the fit and functionality before finalizing the design.
