Very easy adapters for Z axis MGN12H linear rails. I suggest to make the two adapters in aluminium with CNC machining for best strenght (since they are structural parts) but if you want to print them, use ABS (as much perimeters as you can) or PC with threaded inserts (I have not tried this ways, I just suppose that it may work) These adapters does not require moving out the X axis supports using T-nuts because the holes are placed exactly in the same position of the old wheels but you still need to move the X-axis stepper to the opposite side because of interference with the rail (see update below). *UPDATE 23/05/21 : Since it was requested, I added a very simple L shaped bracket I used to move the X-axis stepper on the other side. If you print it remember to use more perimeters and a high infill ratio. I've added 2 holes on the top side for M3 threaded nuts if you need to add a limit switch (just a predisposition since i'm using 2209 drivers with sensorless homing ability. I will add a bracket for the original sensor asap)*
