According to the Doepfer specs, the mounting hole on the left side of the panel should be 7.5mm from the edge (1.5HP minus the kerf/clearance of the panel width). Design version 1.0.1 has the hole at 5.08mm. The hole on the right is also misaligned by 0.5HP.

This means the module either fits excessively snugly against the module on one side of it or it has to be mounted with a 0.5HP gap on both sides.

For the main board and control board, adjust height to at most 100mm to reduce printing cost
