This is a debit card sized storage solution for your needle and thread. This way, you can put your basic sewing tools safely in your pocket. There is room for 4 different thread and 8 needles. 

The threads can be secured with the small notches. The needles are secured by a door, which can be unlocked by pulling the flat surface towards you (not by rotating.) Once the door is unlocked can it be rotated.

It is print in place. There are long bridges so PLA is prefered (I used Prusament Jet Black in the picture). First layer should be 0.18mm, and other layers should be 0.1 mm.
