Mine is installed in a FWC pedalboard case (flightcasewarehouse.co.uk). The case includes a 9mm removable board. I cut a hole in this removable board at the exact dimensions of the MFC101. This way, I insert the MFC101 into the hole and since the board has a 9mm height, it does not move. Since the case is just a few mm deeper than the MFC 101' it does not move during transport. At the same time this system allows me to keep the MFC 101 free of glue, velcro, ... And I can take it out easiliy whenever needed.
I decided to get a large case so I could also attach on the removable board expression pedals and external switches.
Very happy with the setting.
(Cutting the hole to the perfect dimensions is not the easiest part as you can imagine, but still feasible if you take time).
