Couldn't fit the original by MikeFlier on my MINI so I redesigned it.
Ended up modelling it from scratch, which was a nice little challenge for a Fusion noop.
Kept the naming convention from the original design
Each files contains one Bottom, Middle and Top piece.
I did not design any versions of the braces.
Holes sizes goes from 16,5 mm - 27 mm.
27 mm is probably the highest without bigger design changes.
Let me know if you need any other specific diameter for the holes.
The author remixed this model.
Redesigned to fit on a MINI build plate 18x18 cm.
Gab/bridge is shorter and the box sections are smaller.
