Customizable Impact Bit Holder

A customizable impact drill bit holder, inspired by @penguindantro: https://www.thingiverse.com/thing:4536557

1) You can customize how many holes on x axis and y axis
2) You can cut an optional pool to hold screws or special bits
3) I use round holes instead of hex ones to simplify the design and printing
4) You can print the test stl first to ensure your bits can fit into the hole

No support needed.
