Compact box to store the self-centring drill bits that I bought from Amazon (https://www.amazon.co.uk/gp/product/B0B5K23D1H/).

Fits the 3 bits as well as the hex/allen key.

I've added a tab on each end to stop the lid coming off so easily as well as a shadow line so the fit looks nicer (but also doubles as a place to get fingernails under to pry open).
