CR-10 Dual Z stepper sync timing belt brackets

UPDATE: New Version 2 Released, Featuring Zero Height and Increased Y Direction Play This innovative bracket is specifically designed to hold existing bearings and bolts, with a slight modification. The brackets are now positioned approximately 1 cm below their original location, fitting snugly into the vertical profiles instead of the upper horizontal profile. This clever design allows for some of the Z lead screws to extend above them, enabling the addition of two 20-tooth GT2 pulleys and a 76 cm GT2 timing belt between the two Z lead screws. For those seeking even more play in the Y direction, simply let us know, and we'll be happy to accommodate your request. Pulleys for this design can be easily sourced from Aliexpress at [https://www.aliexpress.com/item/GT2-Timing-Pulley-16-Tooth-2GT-20-Teeth-Aluminum-Bore-5mm-8mm-Synchronous-Wheels-Gear-Part/32844125364.html?spm=a2g0s.9042311.0.0.TFusEb](https://www.aliexpress.com/item/GT2-Timing-Pulley-16-Tooth-2GT-20-Teeth-Aluminum-Bore-5mm-8mm-Synchronous-Wheels-Gear-Part/32844125364.html?spm=a2g0s.9042311.0.0.TFusEb) Timing belts for this design can be found at [https://www.aliexpress.com/item/LUPULLEY-GT2-Belt-Rubber-Synchronous-Transmission-Closed-Loop-Belt-300-303-305-308-320-335-348/32824053502.html?spm=a2g0s.9042311.0.0.Zfv6H4](https://www.aliexpress.com/item/LUPULLEY-GT2-Belt-Rubber-Synchronous-Transmission-Closed-Loop-Belt-300-303-305-308-320-335-348/32824053502.html?spm=a2g0s.9042311.0.0.Zfv6H4) Important Note: This bracket consumes approximately 0.5 cm of Z height, but if you're using frame braces, this loss is already accounted for. However, with a bit of optimization, you can regain some of this space by lifting the bearings and utilizing a longer coupler on the stepper motors. Important Reminder (Again): This design requires that you've updated to two Z-axis steppers and lead screws beforehand, either through Tinymachines, Creality, or if your CR-10s has the same distance between the lead screws.
