## Abstract

A filament outlet device for installing on a filament storage device is provided, which includes a first outlet for a first filament having a first diameter; and a first outlet cover, configured to open or close the first outlet; the first outlet cover includes a second outlet for a second filament having a second diameter.

## Claims

### Claim 1

A filament outlet device for installing on a filament storage device, comprising:
a first outlet for a first filament having a first diameter; and
a first outlet cover, configured to open or close the first outlet, wherein
the first outlet cover includes a second outlet for a second filament having a second diameter.

### Claim 2 (depends on 1)

The filament outlet device according to claim 1, wherein the first diameter is larger than the second diameter.

### Claim 3 (depends on 1)

The filament outlet device according to claim 1, wherein
the first outlet includes a first clamping structure to clamp the first filament extending from the first outlet; and
the second outlet includes a second clamping structure to clamp the second filament extending from the second outlet.

### Claim 4 (depends on 3)

The filament outlet device according to claim 3, wherein the first outlet includes a first filament hole with a diameter smaller than the first diameter.

### Claim 5 (depends on 3)

The filament outlet device according to claim 3, wherein the first outlet further includes multiple slits radiating from an inner edge of the first filament hole, forming multiple diaphragms to clamp the first filament.

### Claim 6 (depends on 3)

The filament outlet device according to claim 3, wherein the second outlet includes a second filament hole with a diameter smaller than the second diameter.

### Claim 7 (depends on 3)

The filament outlet device according to claim 3, wherein the second outlet further includes multiple slits radiating from an inner edge of the second filament hole, forming multiple diaphragms to clamp the second filament.

### Claim 8 (depends on 3)

The filament outlet device according to claim 3, wherein the first outlet cover is capable of hermitically closing the first outlet.
