This mounting base can be magnetically or mechanically mounted. The mounting holes for the 2560 can be tapped for machine screws, but I used #4x.5'' wood screws. The 12x3mm magnets are glued in with CA glue.
The Fusion 360 file is not parametric, but it should be fairly easy to modify if you need to make alterations.
