Metric hex key support

A quick design for a metric hex key set I had around the printer. I wanted them stuck on the side of the printer by magnets. So, I made this thing. Fist iteration, feel free to improve/suggest improvements.

Changes:

1. Made the back slots for magnets cylindrical and evenly spread put for better grip.

2. Text string is now supported so there is no need for supports when printing.

3. Changed orientation of hexagons so that now the hex keys are facing forward instead of a 45° angle.

4. Increased clearance for hole to +.6 mm for each hexagon to keep insertion process smooth and effortless.
