A remixed cover for Olef's case design that allows for mounting either a 40mm fan, or a 50mm fan via the adapter.
Requires the base and optional bracket parts from the original setup.
Shown with a 50mm fan from ThePiHut and a parametric fan grill from https://www.thingiverse.com/thing:2491499.
The fan adapter mounts via M3 hardware that screws directly into the part. The holes are sized for thread cutting (2.7mm).
A 40mm fan, or the adapter can be mounted to the case front via CSK M3 hardware coming from within the case lid.
