Thiết bị thông tắc vòi bơm keo silicone

Used to pull set / hardened caulk from a used nozzle. Simply remove the nozzle from the tube, wind the unblocker tool in and pull out the old caulk. Used to restart a tube with nozzle that hasn't been used in some time.

Printed with 0.2mm layer height in PETG, 25% infill, 3 perimeters,  supports ON with brim.

UPDATE: Added Version 2:

• Changed to solid handle to help with printing and not requiring supports
• I still recommend printing horizontally for strength (requires supports along shaft)
• Thickened the shaft and threads for better strength and grip on the caulk
