This is remix of the tophat from the ERCF V2 inspired from the bearing Jack Rabbit mod.
You need to print the bearing holder from this mod and my Tophat because the one part of that mode don't fit en the V2.
No need to add support, they are part of the design just like in the original ERCF V2 files.
The author remixed this model.
Top hat modified to be compatible with the bearing selector mod.
