CR-10 Dual Z timing belt sync brackets v2

thingiverse

Update: I found that this mod still causes the top of the z-screw to bind. I have designed a new one from scratch that uses skateboard bearings and has plenty of clearance to prevent binding here: https://www.thingiverse.com/thing:3532138 This is a remix of the Dual Z Timing Belt Sync Bracket by hoegge. I changed the hole that takes the bearing so that it is elongated to allow for the bearing to move perpendicular to the z extrusion. This allows for play in the spacing between the z extrusion and the z screw. I made this change because the original design by hoegge pushed my z screw out too far from the z extrusion at the top which caused the z axis to bind as the x gantry was moved higher. This might only be an issue with my machine, maybe my z screw is bent or out of alignment but it looks like the original brackets are just a bit too far out. Everything else is the same as hoegge's design, it still uses the 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.
