Carrera digital Brigepier Lego Compatible

I recently discovered a problem with my stabable Bridgepier (stl on my profile). On Cross lanes you cant use it so i designed one that goes directly under the lanes. Also with the cross to attach it with no vibrations during driving. You need to have a good calibrated first layer for it so the Lego Brick fits.
