CR-6 SE Frame Brace Bracket
Description
I wanted something to make the CR-6 SE a bit more rigid similar to the Ender 3 Z axis supports I've been seeing online. I saw a bunch of super DIY ways to do this, but they involved purchasing really long threaded rod, or aluminum rods, cutting them down to size with a saw, etc. I think my solution with just a DIY printed bracket and spacer paired with an off-the-shelf solution and included hardware for the rest makes it a lot easier. I took inspiration from [thing:4107804](https://www.thingiverse.com/thing:4107804) for the way that I could hook into the end of the extrusion on the upper frame. I had to tweak it a bit since the CR-6 SE has closed slots on the front, and the rear side is blocked (already used for the dual Z axis screw stabilizers) REQUIRED PARTS: ==================== * *Printed Brackets* (left and right separately) * *Printed Spacers (2)* * *Ender 3 Dual Z-Axis Support Kit* (I used https://www.amazon.com/dp/B08SJRQD21) There are similar ones online, I've only used this one so mileage may vary with other kits. *PRINT ORIENTATION:* See images for example recommended print orientation. Strength will be compromised if printed in other orientations. If you print this with the other orientation (which is tempting due to less support needed) this will be likely to break along the layer lines where it hooks into the frame extrusion. --------------------- Installation Steps: ==================== * Pick a side to start with, for example left side. * Use the hex key to completely unscrew and remove the top two screws at the top corner of the printer. * Slide the correct bracket onto the corner of the printer. Use care to align the top so that everything slots in correctly. Depending on fitment it may slide in effortlessly, or take some force such as a small hammer or side of your hand. The bracket will be fully in place when it is now flush to the side of the corner and the two holes at the top line up with the screw holes. * Use the hex key to screw in the two top screws that you had previously removed. * Screw the 40mm threaded rod into the 3D printed spacer that goes between the support rods. It should be even on both sides with about 5mm on each end (as pictured) * Assemble the support rods together firmly. * Attach the support rods to the metal bottom bracket as instructed with your kit. * (Please use care in this step, the threads are 3D printed plastic) Attach the support rods to the top 3D printed brackets as you would normally (as if they were the included top corner brackets) this may require you to turn the top threaded portion around to line up with the hole. * Tighten all screws and nuts to ensure a solid connection. (use care to not overtighten) * Optionally use a screw and T-nut to secure the bottom screw on the bracket to the printer. Placing the T-nut into the groove and sliding it up and aligning it with the screw may take a few tries to get lined up correctly.
