FBG/Rail (BCJ) left motor mount CFS update for K1,K1Max,K1C,K1SE,K1A

Attention!!! I do not know the distances from the back wall to the new silicone brush and the plastic drop-off point when CFS replacing filament. At the moment, I can assume that for the modifications with rails, it will be necessary to model and print a different version of the plastic drop-off point, because the original carriage is 23mm wide, while the rail modifications (BCJ, HDM, Kemsky) are 14mm wider than the original carriage.

A simplified model for mounting a new part called 'cutter block' for K1 Series printers. If you have installed Rail/FBG,and want to buy CFS with K1 Series Kit, this part is really necessary for you. The model is still in development; I haven't received my CFS yet

For the former belt tensioner use 4x M3 Voron Brass nuts(M3*OD5*L4) to secure the cutter block. Use 2x(or 4x) stock m3x16 shcs screws
