GridFinity 1/4" Hex Bit Holder with extra storage

This is a remix of FoCo_Phil designed hex bit holder (Link to original model). I have modified for my purposes. It is 20 mm taller so it fits better in the tray I have placed it in. I have also narrowed the holes slightly for a tighter fit (bits still pull out easily). I have made each hole 3 mm deeper (15 mm total depth), which holds taller bits more effectively. I have added 2 slots to hold standard 6" (150 mm) machinist's scale. I have added space within the holder to store spare bits. This space is accessible on the sides of the holder and caps for the openings have been provided on a second printing plate. Since I increase the height of the holder, I have lightened the print cutting away material in a series of 16 square openings (see photo of bottom of holder).
