Don't have any pictures but I made a single much like yours.
Two ways I got the chip problem solved is a G4 and a M8 coolant command to wash it while above it.
And the second way is to make a cover that is spring loaded and tilts away from the tools. This is a complicated one because you have to program the column to push it out of the way before dropping in to take/leave the tool.
I believe some industrial routers have these types of covers available multiple tools.
