Kossel Wire Cable Frame Braces 2020 (Unlock WARP SPEED)

thingiverse

Turn your Kossel from a wobbly tower that rings like a bell into a rock-solid, high-performance printer with these sleek-looking anchors for steel wire frame braces and unlock significant quality or speed boosts - or both. This mod primarily focuses on improving print quality rather than speed; in quantifiable terms, I'd say my ghosting/ringing artifacts for perimeters printed at 40mm/s, 2500mm/s^2, and 10 jerk (inner/outer) are now less visible than they were pre-mod at 30mm/s, 1200mm/s^2, and 5 jerk (outer) + 35 mm/s, 1500mm/s^2, and 10 jerk (inner), resulting in a substantial speed boost for an actual improvement in visible quality. On the other hand, this mod will also enable your printer to withstand extremely high print speeds, and let's face it - which is more fun? It essentially provides the same benefit you'd get from attaching big, thick panels of something stiff to all three sides of your printer. Or close, anyway, and waaaaaay less involved. IMPORTANT DISCLAIMERS: this mod is quick to print, remarkably easy to mount, has a super-cheap BOM, and offers massive and instant benefits, but it comes with the tradeoffs of a moderately reduced build envelope (UPDATE 10.24.18: unless you use these new spreader arms: https://www.thingiverse.com/thing:3173546 -- otherwise it's going to cut off three outside chunks of the build platform somewhere near the inward extent of the horizontal frame members) and the need to really verify your bowden/wiring clearances and look for new potential sources of wear - plus you could theoretically destroy your frame corners if you don't take your time tensioning the setup evenly, although this mod is specifically designed to make it very difficult to apply uneven tension that would wrack your frame to death. Also, I wouldn't recommend doing this mod without also having some compatible corner braces, like mine (https://www.thingiverse.com/thing:2474583), that will transfer twisting moments on the uprights into the horizontals, because otherwise I think this mod could eventually cam the uprights enough to split your corners. But hey, you're a big girl/boy and you want WARP SPEED, right? Read on to the design section and I'll share a semi-secret that's holding you back if you've never monkeyed with the stock Anycubic firmware settings, too! Anywise. Also see the design section for all my reasoning that led to this design. You'll need 3 each of the adjustable and fixed anchors, 3 of the screw adjust mounts, 6 clamp washers, and 1 double eye join, plus: - 1/16" steel cable (about 4.5 meters for an AnyCubic Kossel XL, or estimate by taking your frame's top to bottom diagonal measurement times 6 + 10%). - 3x M5x20 bolts (socket head) - 6x M5x12 bolts (socket head) - 9x M5 nuts - 15x M4x12 bolts (socket head) - 15x M4 nuts - 4x wire clips (preferably the screw-on kind, not the permanent ones) to fit the wire - Drinking straws in your favorite color - Wire strippers
