Linear rail carrier holder for BLV MOD with igus TWE-04-12

I had serious problems with the mgn12H rails from Aliexpress and bought some
350 mm T-linear rails from igus : (TS-04-12) and they are alright for the Z-Axis - didnt try X or Y !
Combined with their TWE-04-12 carrier it is only usable with a slightly edited 2020_left/right_holder from the BLV_mod
