No one else has done it, so it fell to me to make this happen. Hopefully it works out. It has not currently been tested but I will test it soon. The MK3 version works and this was just me adding the x-axis end-stop arm to that, which in theory is all that was needed to adapt the design to the MK2.5.
X-Axis End-Stop Arm
Just added the x-axis end-stop arm to the MK3 x-carriage designed by drodfro.
No .STEP File
This was produced using the "BMG Extruder Carriege for Prusa i3 MK3 Short and Bearing Version" .STL file for the Bear x-carriage. The .STEP file provided by drodfro is incorrect. Therefore I cannot provide a .STEP file.
