I am using the MFC-101 on a Temple Audio Duo Pedalboard with 4 Large Plates for attachment.
For me it`s the optimal MFC + Pedalboard Solution. Very clean and sturdy and easy to handle.
You need to remove the bottom rubber feet and replace the screws with
M3.5 x 6mm flat head screws. The right screws are available on the FAS Parts Shop:

The following thread is a good source for further information on removing the MFCs feet for Pedalboard attachment:
