Bitholder hexagonal Nuts

This Holder/Storage i constructed because of less place in my tool storage. I don´t like boxes where i have to search the rigt bit for a long time. There, all Bits are keeped in a good order.
A velcro-tape is used to hold the rolled storage together. If you want to use the bits, remove the velcro-tape and all bits are laying in order in a line - perfect! The round cup i printed former for the cupholder of my Corolla (download there, if you are interested).
