For Drag Chains 10x11mm.afterburner or stealth burner with a orbiter 2.0 for a ender 3 should work on v2 ,,pro cr10s ect with rail .. left exit or right. as pictured . the orbiter can get hot so petg or abs is recommend .m3 bolt can tread in or you can run a m3 all the way with a nut .
the motor cover part was a remix i can't say with 100% but i believe its from kevinakasam.the ender 3 belted z guy found it in a form post that lead me down a path a while ago .
