Sewing Machine Thread Spool

• Updated to v.1.5. Reinforced locking cone. This side is completely flush. On the opposite side, the tube is extended by 0,5mm. 

Spare sewing machine thread spool  to rewind thread from big one (for overlock machine) to home sewing machine. The spool does include thread locking (parking) on one side. 

To rewind the thread, I used a M6 x 70 mm screw and a M6 nut to hold the spool. The job is done by help of a drill machine. 

No print support is needed. Inspect and clean it with a scalpel after printing.
