How to use:
---Trim the two filament heads that need to be connected
---Straight from the direction of the large end of the filament connector to the end of the scale.
---The other end is straight from the direction of the small head to the exposed 1-2mm.
---Burn on fire for 5-7 seconds.
---Quickly push the filament from the small end into the small hole in the big end slowly.
---Pull back slowly, back and forth a few times.
---After the filament is completely cooled, the filament is pushed out completely from the small end until it can be easily trimmed.
(If the filament is not smooth enough, you can gently trim it with a knife.)
---Test results after repair (carefully bend joint - stretch - bend - stretch).
(If you hear a crisp sound, reconnect.)

Attention:
1.The more filaments used, the more severe the final bending, and the greater the strength of the rebound.
2.The harder the material, the longer it will burn.
3.Do not wait until the end of the filament is very close to the extruder.
4.When in use, push from the small end to the big end.

The package include:
2 X filament connectors
