CR-10 Dual Z stepper sync timing belt brackets

thingiverse

UPDATE: New version 2, that does not take any height (Z size) and has more Y direction play. This is brackets to hold the existing bearings and bolts, but moved apx 1 cm down fitting in the vertical profiles instead of in the upper horizontal profile. This way there is some of the Z lead screws extending out above them so you can add two 20 teeth GT2 pullies (8 mm bores to fit the lead screw) and a 76 cm GT2 timing belt between the two Z lead screws. If you want a version with more play in the Y direction, let me know.

If you use the (almost mandatory) frame braces, this distance is lost already, but you could probably optimize this by lifting the bearing 0.5 cm and also by using a longer coupler at the bottom on the stepper motors. NB (again): This requires you have updated to two Z axis steppers and lead screws beforehand - either by the update Tinymachines, from Creality or if you have bought the CR-10s, which I assume have same distance between the lead screws.
