hello. Does any one have the stl or stp file for the dual flex3drive. I build an blv mgn AM8 with one extruder. I want to upgrade it to dual with a cyclops chimera. I visited F3D website. but the flex3drive dual page is dead. I contact them but have no answer so far. I need the stl or stp file to re-design the x carriage. So if someone can share it with me, i will apriciate it a lot. Thank you iby Benforj - General
