This model is a REMIX of Shawn's Werkzeug pin vise case model.
This case hold a pin vise and up to 6 different size bits, 3mm(1/8") and smaller, including a spot for a holder that stores even smaller bits.
I modified the original case for a pin vise I bought on Aliexpress that included 50 drill bits of 5 various sizes and a case that holds 0.1mm - 1.0mm bits.
The left area for the smaller bits holder has an indent that allows it to be pushed down and raised in order to be removed from the case.
The author remixed this model.
The case is bigger to holder more bits including an area for another case to be stored
